Evaluation of Constitutional Provisions and their respective Parts:

• Part VIII: The Union Territories (Articles 239 to 242). Correctly matched.
• Part X: The Scheduled and Tribal Areas (Articles 244 to 244A). Correctly matched.
• Part XIV-A: Tribunals (Articles 323A and 323B, inserted by the 42nd Amendment Act, 1976). In contrast, Part XI deals with Relations between the Union and the States (Articles 245 to 263). Therefore, matching Tribunals with Part XI is INCORRECT.
• Part XVII: Official Language (Articles 343 to 351). Correctly matched.

Hence, the provision not correctly matched is Tribunals — Part XI (Option C).

Detailed match between Constitutional Articles and their Bodies:

| List-I (Article) | List-II (Body) |

| :--- | :--- |

| A. Article 324 | 4. Election Commission |

| B. Article 315 | 3. Public Service Commission |

| C. Article 280 | 2. Finance Commission |

| D. Article 338 | 1. National Commission for Scheduled Castes |

• Article 324: Superintendence, direction, and control of elections vested in an Election Commission.
• Article 315: Public Service Commissions for the Union and for the States (UPSC and State PSCs).
• Article 280: Constitution of the Finance Commission by the President every five years.
• Article 338: National Commission for Scheduled Castes (NCSC) [Art 338A is NCST, Art 338B is NCBC].

Hence, the correct matching code is 4, 3, 2, 1 (Option B).

Chronological order of milestone events in the making of the Indian Constitution:

1. Constituent Assembly first met (IV): 9 December 1946 in the Constitution Hall (Central Hall of Parliament), New Delhi, presided over by interim temporary President Dr. Sachchidananda Sinha.
2. Appointment of the Drafting Committee (I): 29 August 1947, when the Constituent Assembly appointed a seven-member Drafting Committee under the chairmanship of Dr. B.R. Ambedkar.
3. Adoption and enactment of Indian Constitution (II): 26 November 1949, when the Constitution was formally adopted, enacted, and given to themselves by the people of India (celebrated as Constitution Day).
4. Commencement of the Indian Constitution (III): 26 January 1950, when the Constitution of India became fully operational, commemorating the 1930 Purna Swaraj Day.

Correct chronological sequence: IV → I → II → III (Option B).

Constitutional mechanism under Article 3 for changing state boundaries:

• Assertion (A) is true: Under the Proviso to Article 3, no Bill for altering the boundary or name of any State shall be introduced in either House of Parliament except on the recommendation of the President, and where the proposal affects the area, boundaries, or name of any State, the Bill must be referred by the President to the Legislature of that State for expressing its views within a specified period.
• Reason (R) is true: The views expressed by the State Legislature are purely advisory. It is not mandatory for the President or the Parliament to accept or act upon the views/proposals of the State Legislature; Parliament can proceed to enact the Bill even if the State opposes it (Babulal Parate v. State of Bombay, 1960).

While both statements are correct constitutional facts, Reason describes the non-binding nature of the state's views rather than the causal origin of the referral procedure in A. Hence both are true, but R is not the correct explanation of A (Option B).

Constitutional jurisprudence under Article 71(2) regarding the invalidation of Presidential / Vice-Presidential elections:

• Under Article 71(1), all doubts and disputes arising out of or in connection with the election of a President or Vice-President are inquired into and decided by the Supreme Court, whose decision is final.
• Statement 1 is correct: Article 71(2) explicitly provides: 'If the election of a person as President or Vice-President is declared void by the Supreme Court, acts done by him in the exercise and performance of the powers and duties of the office of President or Vice-President, as the case may be, on or before the date of the decision of the Supreme Court shall NOT be invalidated by reason of that declaration.' This ensures legal certainty and continuity of state actions.
• Statement 2 is incorrect: Acts done on the day of the decision are explicitly protected under the constitutional phrase 'on or before the date of the decision'. They do NOT become invalid.

Therefore, only statement 1 is correct.

First Woman Speaker of the Lok Sabha:

• Meira Kumar was unanimously elected as the first woman Speaker of the Lok Sabha on 3 June 2009 during the 15th Lok Sabha (serving until 2014).
• A former diplomat (IFS officer) and senior parliamentarian from Bihar, she was the daughter of legendary nationalist leader and former Deputy Prime Minister Babu Jagjivan Ram.
• (Sumitra Mahajan was the second woman Speaker, presiding over the 16th Lok Sabha from 2014 to 2019; Pratibha Patil was the first woman President of India; Sushma Swaraj was a prominent Union Cabinet Minister).

Therefore, the first woman Speaker in Lok Sabha was Meira Kumar (Option C).

Evaluation of Schedules and their Subjects in the Indian Constitution:

• Third Schedule: Forms of Oaths or Affirmations for constitutional functionaries. Correctly matched.
• Eighth Schedule: List of 22 constitutionally recognized languages. Correctly matched.
• Ninth Schedule: Validation of certain Acts and Regulations (originally land reforms, inserted by 1st Amendment 1951). In contrast, Allocation of seats in the Council of States (Rajya Sabha) is governed by the FOURTH SCHEDULE, NOT the Ninth Schedule. Therefore, pair C is INCORRECTLY matched.
• Tenth Schedule: Provisions as to disqualification on ground of defection (Anti-Defection Law, 52nd Amendment 1985). Correctly matched.

Hence, the pair not correctly matched is Ninth Schedule (Option C).

Constitutional provisions regarding the official language under Article 343:

• Article 343(1) declares Hindi in Devanagari script to be the official language of the Union.
• Article 343(2) explicitly provided that for a period of fifteen years (15 years) from the commencement of the Constitution (i.e., from 26 January 1950 to 26 January 1965), the English language would continue to be used for all the official purposes of the Union for which it was being used immediately before such commencement.
• Article 343(3) empowered Parliament to provide by law for the continued use of English beyond 15 years, which Parliament did via the Official Languages Act, 1963.

Therefore, the Constitution initially permitted English for 15 years (Option C).

Composition and legislative nature of Parliament under Article 79:

• Assertion (A) is true: Article 79 unequivocally states: 'There shall be a Parliament for the Union which shall consist of the President and two Houses to be known respectively as the Council of States and the House of the People.' Thus, the President of India is an integral component of the Parliament.
• Reason (R) is true and gives the correct explanation: Under Article 111, when a Bill has been passed by both Houses of Parliament, it must be presented to the President, and it cannot become an enforceable Act (law) without receiving the assent of the President. Because legislation is the primary function of Parliament and cannot be completed without the President's formal assent, the President is organically integrated as part of Parliament itself. Thus, (R) is the exact constitutional explanation of (A).

Constitutional provisions regarding the Finance Commission under Articles 280 and 281:

1. Statement 1 is incorrect: Under Article 280(1), the Finance Commission consists of a Chairman and FOUR other members (total of 5 members), NOT six members. (The qualification of the Chairman and four members is regulated by the Finance Commission [Miscellaneous Provisions] Act, 1951).
2. Statement 2 is incorrect: Under Article 281, the Finance Commission submits its recommendations and explanatory memorandum to the President of India, who causes it to be laid before each House of Parliament. It does NOT submit its report to NITI Aayog (NITI Aayog is a non-statutory policy think tank, not the recipient of constitutional commission reports).

Therefore, neither 1 nor 2 is correct.

Constitutional scope of writ jurisdiction under Article 32:

1. Statement 1 is correct: Under Article 32(2), the Supreme Court has the power to issue directions, orders, or writs, including writs in the nature of Habeas Corpus, Mandamus, Prohibition, Quo Warranto, and Certiorari, whichever may be appropriate, for the enforcement of any of the Fundamental Rights guaranteed by Part III.
2. Statement 2 is correct: Under Article 32(3), without prejudice to the powers conferred on the Supreme Court by clauses (1) and (2), Parliament may by law empower any other court to exercise within the local limits of its jurisdiction all or any of the powers exercisable by the Supreme Court under clause (2). (High Courts exercise writ powers independently under Article 226).

Therefore, both statements 1 and 2 are correct.

Constitutional office of the Attorney General for India under Article 76:

1. Statement 1 is correct: Under Article 76(1), the President shall appoint a person who is qualified to be appointed a Judge of the Supreme Court to be Attorney General for India (i.e., must be a citizen of India, having been an advocate of a High Court for 10 years or a judge of a High Court for 5 years, or an eminent jurist).
2. Statement 2 is incorrect: Under Article 76(4), the Attorney General holds office during the pleasure of the President and receives such remuneration as the President may determine. He is NOT removed through the judicial impeachment process applied to Judges of the Supreme Court (Article 124(4)); he can be removed by the President at any time without assigning cause, and conventionally resigns when the government resigns.

Therefore, only statement 1 is correct.

Composition of the State Legislative Council (Vidhan Parishad) under Article 171:

1. Statement 1 is correct: Under Article 171(1), the total number of members in the Legislative Council of a State having such a Council shall not exceed one-third (1/3) of the total number of members in the Legislative Assembly of that State.
2. Statement 2 is correct: Article 171(1) further provides that the total number of members in the Legislative Council of a State shall in no case be less than forty (40).

Therefore, both statements 1 and 2 are correct.

Parliamentary representation of Uttar Pradesh in Parliament:

1. Statement 1 is correct: Under the Fourth Schedule of the Constitution, Uttar Pradesh is allotted 31 seats in the Rajya Sabha (Council of States), which is the largest representation of any state in India.
2. Statement 2 is correct: Under the Delimitation Order and First Schedule of the Representation of the People Act, 1950, Uttar Pradesh elects 80 members to the Lok Sabha (House of the People), which is also the largest representation of any state in India.

Therefore, both statements 1 and 2 are correct.

Constitutional provisions regarding the Secretariat of Parliament under Article 98:

1. Statement 1 is correct: Article 98(1) provides that each House of Parliament shall have a separate secretarial staff; provided that nothing in this clause shall be construed as preventing the creation of posts common to the Secretariat of both Houses of Parliament.
2. Statement 2 is correct: Under Article 98(2), Parliament may by law regulate the recruitment, and the conditions of service of persons appointed, to the secretarial staff of either House of Parliament.

Therefore, both statements 1 and 2 are correct.

Constitutional and statutory framework of the Gram Sabha under Article 243A:

• Article 243(b) defines Gram Sabha as a body consisting of persons registered in the electoral rolls relating to a village comprised within the area of Panchayat at the village level. (Statement C is true).
• Under Article 243A, a Gram Sabha may exercise such powers and perform such functions at the village level as the LEGISLATURE OF A STATE may, by law, provide. (Statement A is true).
• Statement B is false: The powers and functions of the Gram Sabha are determined exclusively by the State Government / State Legislature, NOT by the Central Government. Panchayati Raj is listed under Entry 5 of the State List (List II) of the Seventh Schedule.

Therefore, the statement that is NOT true is Option B.

Constitutional authority conducting Panchayat elections under Article 243K:

• Under Article 243K(1) (and Article 243ZA for municipalities), the superintendence, direction, and control of the preparation of electoral rolls for, and the conduct of, all elections to the Panchayats are vested in the State Election Commission consisting of a State Election Commissioner appointed by the Governor.
• The Election Commission of India (Article 324) conducts elections only for the President, Vice-President, Parliament, and State Legislatures, NOT for Panchayats or Urban Local Bodies.

Therefore, all elections to the Panchayats are conducted by the State Election Commission (Option B).

Recommendations of the Ashok Mehta Committee on Panchayati Raj (appointed December 1977, submitted August 1978):

1. Statement 1 is correct: The committee recommended that the existing three-tier system of Panchayati Raj (instituted by Balwant Rai Mehta) should be replaced by a two-tier system: the Zilla Parishad at the district level, and below it, the Mandal Panchayat comprising a group of villages covering a population of 15,000 to 20,000.
2. Statement 2 is incorrect: The committee recommended that the DISTRICT (Zilla Parishad)—NOT the Block—should be the first point for decentralization under popular supervision below the state level, with planning executive authority vested in the Zilla Parishad.

Therefore, only statement 1 is correct.

Constitutional resignation procedure under Article 124(2)(a):

• Under Proviso (a) to Article 124(2) of the Indian Constitution, a Judge of the Supreme Court of India may, by writing under his hand addressed to the PRESIDENT OF INDIA, resign his office.
• (Similarly, a Judge of a High Court addresses his resignation letter to the President under Article 217(1)(a)).
• A Judge does NOT address his resignation to the Chief Justice of India or the Prime Minister.

Therefore, the resignation letter is addressed to The President (Option C).

Constitutional protections against arbitrary prosecution under Article 20:

• Article 20 consists of three distinct fundamental clauses:

1. Article 20(1): Protection against Ex-post Facto Law (no person convicted of any offence except for violation of a law in force at the time of commission).
2. Article 20(2): Protection against Double Jeopardy (no person prosecuted and punished for the same offence more than once).
3. Article 20(3): Prohibition against Self-Incrimination (no person accused of an offence compelled to be a witness against himself).

• 'Prohibition Against Torture' is NOT an enumerated clause of Article 20. (Freedom from torture is judicially derived from the Right to Life and Personal Liberty under Article 21 and international conventions like UNCAT).

Therefore, the clause not part of Article 20 is Prohibition Against Torture (Option D).

Environmental protection in the Constitution across both DPSP and Fundamental Duties:

• Directive Principles of State Policy (DPSP): Article 48A (inserted by 42nd Amendment, 1976) mandates: 'The State shall endeavour to protect and improve the environment and to safeguard the forests and wild life of the country.'
• Fundamental Duties: Article 51A(g) (also inserted by 42nd Amendment, 1976) mandates that it shall be the duty of every citizen of India 'to protect and improve the natural environment including forests, lakes, rivers and wild life, and to have compassion for living creatures.'
• Therefore, 'Protection and improvement of the environment' is the common provision enshrined in both Part IV (DPSP) and Part IV-A (Fundamental Duties).

Hence, Option B is correct.

Constitutional mechanism for the Joint Sitting of Parliament:

1. Statement 1 is incorrect: The constitutional provision for a Joint Sitting of both Houses to resolve legislative deadlock is laid down in Article 108, NOT Article 109. (Article 109 deals with special procedure regarding Money Bills).
2. Statement 2 is correct: Under Article 118(4) of the Constitution, at a joint sitting of the two Houses, the Speaker of the House of the People (Lok Sabha), or in his absence such person as may be determined by rules of procedure (Deputy Speaker, or if also absent, Deputy Chairman of Rajya Sabha), shall preside.

Therefore, only statement 2 is correct.

Chronological order of foreign invaders into Ancient India:

1. Indo-Greeks (Bactrian Greeks) (c. 2nd Century BCE): First to invade northwestern India following the collapse of the Mauryan Empire (led by Demetrius and Menander I / Milinda); first rulers to issue gold coins bearing portraits and legends in India.
2. Sakas (Indo-Scythians) (c. 1st Century BCE to 1st Century CE): Nomadic pastoralists driven from Central Asia who established regional satrapies across Taxila, Mathura, Ujjain, and western India (famous ruler: Rudradaman I of Junagarh rock inscription).
3. Kushans (Yuezhi tribe) (c. 1st Century CE): Originating in northwestern China/Central Asia; founded a vast empire under Kujula Kadphises, Vima Kadphises, and Kanishka I (who convened the 4th Buddhist Council in 72 CE).

Correct chronological sequence: Greeks → Sakas → Kushans (Option A).

Milinda Panha (Questions of King Milinda):

• Milinda Panha is a celebrated non-canonical Pali Buddhist text structured as a philosophical dialogue between the Indo-Greek King Menander I (Milinda), who ruled from Sagala (modern Sialkot, Pakistan), and the erudite Buddhist sage and Arhat Nagasena.
• King Milinda poses deep epistemological and metaphysical questions regarding the nature of the self (Anatta), rebirth without a soul, karma, and Nirvana. Highly satisfied with Nagasena's brilliant chariot allegories and answers, Menander embraced Buddhism as a lay devotee.

Therefore, the concerned Buddhist saint was Nagasena (Option C).

Structure of the ancient medical treatise Charaka Samhita:

• Authored/redacted by Maharshi Charaka (court physician of the Kushan King Kanishka), the Charaka Samhita is the foundational canonical encyclopedia of internal medicine (Kayachikitsa) in Ayurveda.
• The treatise is organized into exactly 120 Chapters (Adhyayas) systematically grouped into 8 Sections (Sthanas):

1. Sutra Sthana (30 chapters - pharmacology & dietetics)
2. Nidana Sthana (8 chapters - pathology & diagnosis)
3. Vimana Sthana (8 chapters - epistemology & dosage)
4. Sharira Sthana (8 chapters - embryology & anatomy)
5. Indriya Sthana (12 chapters - prognosis)
6. Chikitsa Sthana (30 chapters - therapeutics & treatment)
7. Kalpa Sthana (12 chapters - pharmacy)
8. Siddhi Sthana (12 chapters - successful evacuation therapy)

Total: 30+8+8+8+12+30+12+12 = 120 chapters and 8 sections.

Hence, Option A is correct.

In the Later Vedic period, 'Bhagadugha' was one of the king's twelve key royal officials (Ratnins) who functioned as the collector of taxes and revenue.

Detailed match between prehistoric archaeological sites and their present-day states:

| List-I (Archaeological Site) | List-II (State) |

| :--- | :--- |

| A. Nevasa | 3. Maharashtra |

| B. Isampur | 4. Karnataka |

| C. Didwana | 1. Rajasthan |

| D. Gudiyam Cave | 2. Tamil Nadu |

• Nevasa: Located on the Pravara River in Ahmednagar district, Maharashtra (famous Middle Palaeolithic Nevasan culture excavated by H.D. Sankalia).
• Isampur: Located in the Hunsgi-Baichbal valley in Yadgir district, Karnataka (a prolific Lower Palaeolithic Acheulian limestone quarry and tool-manufacturing factory site excavated by K. Paddayya).
• Didwana: Located in the Nagaur district, Rajasthan (key Lower and Middle Palaeolithic site in the Thar Desert).
• Gudiyam Cave: Palaeolithic rock shelter situated near the historic Attirampakkam site in Tiruvallur district, Tamil Nadu (excavated by Robert Bruce Foote).

Hence, the correct matching code is 3, 4, 1, 2 (Option A).

Geographical boundaries of the Indus Valley / Harappan Civilization:

• The Harappan Civilization formed a vast triangular geographic realm covering nearly 1.3 million sq km, with its four cardinal extremities defined as follows:

1. Northernmost boundary: Manda (on the Chenab River in Jammu & Kashmir).
2. Southernmost boundary: Daimabad (on the Pravara River in Maharashtra).
3. Westernmost boundary: Sutkagen Dor (on the Dasht River along the Iran-Pakistan Makran coast in Balochistan).
4. Easternmost boundary: Alamgirpur (situated on the Hindon River, a tributary of the Yamuna, in the Meerut district of Uttar Pradesh).

Therefore, the eastern boundary of the Harappa culture is indicated by Alamgirpur (Option B).

Historical information contained in the classical Puranas regarding royal dynasties:

1. Statement 1 is correct: The Vishnu Purana provides invaluable historical genealogical details and administrative descriptions of the Mauryan dynasty, prominently detailing Chandragupta Maurya and the overthrow of the Nandas by Chanakya.
2. Statement 2 is correct: The Vayu Purana (along with the Matsya Purana) throws rich light on the rise, geographic extent, and governance system of the Gupta dynasty (famously noting that the early Guptas ruled territories along the Ganga, Prayag, Saketa, and Magadha: 'Anugangam Prayagam cha Saketam Magadhams tatha...').

Therefore, both statements 1 and 2 are correct.

Evaluation of the Six Systems of Indian Philosophy (Shad-Darshana) and their Founders:

• Nyaya: Founded by Sage Gautama (Aksapada Gautama, author of Nyaya Sutras). This pair is CORRECTLY matched.
• Vaisheshika: Founded by Sage Kanada (Uluka), NOT Patanjali.
• Yoga: Founded by Sage Patanjali (author of Yoga Sutras).
• Purva Mimamsa: Founded by Sage Jaimini, NOT Kanada.
• Uttara Mimamsa (Vedanta): Founded by Sage Badarayana (Vyasa).
• Samkhya: Founded by Sage Kapila.

Therefore, the correctly matched pair is Nyaya — Gautama (Option C).

Historical mission of Captain William Hawkins to the Mughal Court:

1. Statement 1 is incorrect: Captain Hawkins arrived at the port of Surat aboard the East India Company ship Hector in August 1608, and reached the imperial Mughal court of Emperor Jahangir at Agra in April 1609 (NOT 1611), carrying an official letter of introduction from King James I of England.
2. Statement 2 is correct: Hawkins was fluent in Turki (Chagatai Turkish), which was Jahangir's ancestral mother tongue. Jahangir was delighted to converse directly with Hawkins in Turkish without needing an interpreter, granted him private audience, awarded him a mansab of 400 zat, and bestowed upon him the title 'English Khan'. Hawkins remained at court until 1611.

Therefore, only statement 2 is correct.

Administrative office of 'Khareetadar' (खरीतादार) in Medieval Indian administration:

• In the administrative structure of the Delhi Sultanate, Sur Empire, and provincial kingdoms, a 'Khareeta' was the official silk or brocade pouch/receptacle used for dispatching formal royal letters, decrees, and diplomatic correspondence between rulers, governors, and nobles.
• The Khareetadar was the designated royal official entrusted with the custody, preparation, sealing, and dispatch of royal letters, farmans, and decrees (the Despatcher of Royal Decrees / Head of the Correspondence Department).

Therefore, Khareetadar was the Despatcher of royal decrees (Option A).

Detailed match between Medieval Historical Works and their Context/Subjects:

| List-I (Book) | List-II (Context) |

| :--- | :--- |

| A. Mirat-e-Sikandari | 4. History / Victory of Gujarat |

| B. Burhan-e-Masir | 2. History of Bahmanis and Ahmadnagar |

| C. Riyaz-us-Salatin | 1. History of Bengal |

| D. Riyaz-ul-Insha | 3. Collection of Mahmud Gawan's letters |

• Mirat-e-Sikandari: Written by Shaikh Sikandar bin Muhammad Manjhu (completed 1611); definitive Persian chronicle of the Gujarat Sultanate from its origin to Mughal conquest.
• Burhan-e-Masir: Written by Sayyid Ali Tabataba (completed c. 1599); prime historical source for the Bahmani Sultanate and the Nizam Shahi dynasty of Ahmadnagar.
• Riyaz-us-Salatin: Authored by Ghulam Husain Salim Zaidpuri in 1788; the first comprehensive historical chronicle of Bengal in Persian.
• Riyaz-ul-Insha: The celebrated compilation of official diplomatic letters and personal correspondence composed by Khwaja Mahmud Gawan, the brilliant Prime Minister (Vakil-us-Sultanat) of the Bahmani kingdom.

Hence, the correct matching code is 4, 2, 1, 3 (Option A).

Evaluation of Medieval dynastic and familial relationships:

• Iltutmish — Father of Razia: Correctly matched (Razia Sultan was the chosen daughter and successor of Shams-ud-din Iltutmish).
• Shah Turkan — Wife of Iltutmish: Correctly matched (Shah Turkan was a prominent Turkish concubine-wife of Iltutmish and mother of Rukn-ud-din Firuz).
• Gulbadan Begum — Daughter of Babur: Correctly matched (Gulbadan Begum was Babur's daughter, Humayun's sister, and author of the Humayun-nama).
• Hamida Banu Begum — Wife of Alauddin Khalji: INCORRECTLY MATCHED. Hamida Banu Begum (Maryam Makani) was the wife of Mughal Emperor Humayun and the mother of Akbar (married in 1541), having absolutely no connection with Alauddin Khalji (whose queen was Malika-i-Jahan / Kamala Devi).

Therefore, the pair not correctly matched is Option C.

Chronological order of the ruling Maratha Peshwas:

1. Balaji Vishwanath (I): Ruled from 1713 to 1720 CE (first hereditary Peshwa appointed by Chhatrapati Shahu).
2. Baji Rao I (II): Ruled from 1720 to 1740 CE (celebrated warrior son of Balaji Vishwanath, champion of Hindu Pad-Padshahi).
3. Madhav Rao I (IV): Ruled from 1761 to 1772 CE (4th Peshwa, who revitalized Maratha supremacy after the 1761 defeat at Panipat).
4. Narayan Rao (III): Ruled from 1772 to August 1773 CE (younger brother and successor of Madhav Rao I, assassinated at Shanivar Wada).

Correct chronological sequence: I (Balaji Vishwanath) → II (Baji Rao) → IV (Madhav Rao) → III (Narayan Rao), which is I, II, IV, III (Option D).

Sultan of Kashmir who abolished Jizya and Cow Slaughter:

• Sultan Zain-ul-Abidin (reigned 1420–1470 CE), the eighth Sultan of Kashmir belonging to the Shah Mir dynasty, is revered in history as 'Badshah' (The Great Sultan) and the 'Akbar of Kashmir'.
• Reversing the religious bigotry and persecution of his father Sikandar Butshikan, Zain-ul-Abidin pursued a policy of complete religious tolerance, recalled exiled Kashmiri Pandits, restored destroyed temples, completely abolished Jizya, and prohibited cow slaughter throughout Kashmir.
• He established a translation bureau where the Mahabharata and Kalhana's Rajatarangini were translated into Persian.

Therefore, the ruler was Zain-ul-Abidin (Option C).

Translation of Sanskrit texts under Firoz Shah Tughlaq:

• During his military campaign against the Nagarkot Fort (Kangra, Himachal Pradesh) in 1365 CE, Sultan Firoz Shah Tughlaq captured the famous Jwalamukhi Temple, which housed an extensive ancient library of approximately 1,300 Sanskrit manuscripts on philosophy, astronomy, mathematics, and medicine.
• Firoz Shah commissioned the eminent Persian scholar and court poet Aizzuddin Khalid Khani (Azizuddin Khan) to translate 300 of these selected Sanskrit volumes into elegant Persian verse and prose.
• The resulting famous Persian compilation was titled 'Dalail-i-Firuz Shahi' (Arguments of Firoz Shah), dedicated to natural sciences, astrology, and music.

Therefore, the scholar who translated these books was Azizuddin Khan (Option A).

Refinement of the Tappa musical genre in the Mughal Court:

• Tappa is a distinctive semi-classical vocal style characterized by fast, bouncy, intricate, and quick-rolling ornamentation (taans), which originated from the folk songs of camel drivers in northwestern Punjab.
• It was brought to imperial perfection, refined, and institutionalized in the court of Mughal Emperor Muhammad Shah 'Rangeela' (reigned 1719–1748) by the celebrated court vocalist Ghulam Nabi, famously known as Shori Mian.
• Muhammad Shah was an extraordinary patron of Hindustani classical music, during whose reign Khayal (refined by Sadarang and Adarang) and Tappa attained classical status.

Therefore, Tappa style was refined in the court of Muhammad Shah (Option D).

Evaluation of Medieval Devotional Poetesses and their Compositions:

• Daya Bai — Vinay Malika: Correctly matched (Daya Bai was a renowned female disciple of Sant Charandas in Delhi; author of Daya Bodh and Vinay Malika).
• Sahajo Bai — Sahaj Prakash: Correctly matched (Sahajo Bai was another celebrated female disciple of Sant Charandas; author of the famous spiritual verse treatise Sahaj Prakash).
• Son Kumari — Swarna Beli: Correctly matched (Rajasthan/Braj devotional poetess who composed spiritual verses titled Swarn Beli).
• Gangabai — Ganesh Dev Leela: INCORRECTLY MATCHED. Ganesh Dev Leela is NOT a composition of Gangabai; Gangabai was a Pushtimargiya Vaishnava poetess known for padas dedicated to Radha-Krishna, while Ganesh Dev Leela was authored by other medieval bards.

Therefore, the pair not correctly matched is Gangabai — Ganesh Dev Leela (Option C).

Outbreak dates of the 1857 Revolt across key centres:

• Barrackpore — 29 March 1857: Mangal Pandey of the 34th Bengal Native Infantry mutinied and fired at British officers. Correctly matched.
• Meerut — 10 May 1857: Sepoys of the 3rd Native Cavalry mutinied, broke open the jail, killed officers, and marched to Delhi, marking the formal outbreak of the 1857 Revolt. Correctly matched.
• Lucknow — 4 June 1857: The uprising began under the leadership of Begum Hazrat Mahal, Birjis Qadr, and Raja Jailal Singh. Correctly matched.
• Jhansi — 11 May 1857: INCORRECTLY MATCHED. On 11 May 1857, mutineers reached Delhi and proclaimed Bahadur Shah Zafar. The rebellion in Jhansi broke out on 4–5 June 1857 (when sepoys seized the Star Fort), and Rani Lakshmibai formally assumed active leadership in June 1857. Dating Jhansi to 11 May is completely erroneous.

Therefore, the pair not correctly matched is Jhansi — 11 May, 1857 (Option D).

Formation of the United Provinces Kisan Sabha (1918):

• In February 1918, the United Provinces Kisan Sabha (उत्तर प्रदेश किसान सभा) was founded in Allahabad (Prayagraj) to organize oppressed peasants against arbitrary zamindari evictions (bedakhali), illegal cesses (nazrana), and exorbitant rent hikes.
• It was founded primarily through the active initiative and organizational leadership of Indra Narayan Dwivedi and Gauri Shankar Mishra, with the crucial backing and patronship of Pandit Madan Mohan Malaviya.
• By 1919, the UP Kisan Sabha had established over 173 branches across districts like Pratapgarh, Rae Bareli, Sultanpur, and Faizabad.
• (Baba Ramchandra subsequently led the grassroots Awadh peasant movement and helped establish the Awadh Kisan Sabha at Pratapgarh in October 1920 along with Jawaharlal Nehru).

Therefore, the leader among the options who formed it was Indra Narayan Dwivedi (Option B).

The Delhi Conspiracy Case (1912) and the bomb attack on Viceroy Lord Hardinge:

• On 23 December 1912, during the grand state procession entering the new capital of Delhi through Chandni Chowk, a bomb was hurled at the elephant carrying Viceroy Lord Hardinge II, injuring the Viceroy and killing his attendant.
• The revolutionary mastermind behind this daring conspiracy was Rash Behari Bose, along with Sachindra Nath Sanyal and their revolutionary network affiliated with the Yugantar group (the secret revolutionary society of Bengal with active branches in the United Provinces and Delhi).
• Basant Kumar Biswas, Manmatha Biswas, and Awadh Bihari were among the youths who executed the bombing.

Therefore, the organisation responsible was Yugantar (Option D).

Institution of the Chamber of Princes (Narendra Mandal):

• The creation of a formal consultative council of Indian princely rulers was recommended in the Montagu-Chelmsford Report (1918) and codified under the Government of India Act of 1919.
• Established by a Royal Proclamation of King-Emperor George V on 23 December 1919 and formally inaugurated on 8 February 1921 by the Duke of Connaught at the Red Fort in Delhi, the Chamber of Princes (Narendra Mandal) consisted of 120 members (108 rulers of major princely states in their own right, and 12 representing 127 lesser states).
• Maharaja Ganga Singh of Bikaner served as its first Chancellor.

Therefore, it was created by the Act of 1919 (Option D).

Historical analysis of E.V. Ramasamy Naicker (Periyar):

1. Statement 1 is correct: Periyar joined the Indian National Congress in 1919 and actively participated in the Non-Cooperation Movement (1920–1922). He courted arrest by picketing toddy shops in Erode (even felling 500 coconut trees on his own farm), vigorously promoted Khadi, and led the historic Vaikom Satyagraha (1924) in Travancore demanding temple entry rights for untouchables, earning the title Vaikom Veerar.
2. Statement 2 is correct: Disillusioned with caste conservatism within the Congress (particularly dining segregation at the Cheranmadevi Gurukulam) and the rejection of communal quotas for non-Brahmins, Periyar formally resigned from the Congress at the Kanchipuram conference in November 1925 and founded the pioneering Self-Respect Movement (Swayam Mariyadai Iyakkam).

Therefore, both statements 1 and 2 are correct.

Female Combat Regiment of the Azad Hind Fauj (Indian National Army):

• On 12 July 1943 in Singapore, Netaji Subhash Chandra Bose announced the formation of an all-female combat regiment of the Azad Hind Fauj, named the Rani of Jhansi Regiment.
• Named in honor of the legendary 1857 martyr Rani Lakshmibai of Jhansi, it was one of the world's very first all-female active frontline infantry fighting units in modern warfare.
• Netaji appointed Dr. Lakshmi Swaminathan (Captain Lakshmi Sahgal) as its commander. The regiment was rigorously trained in weapons, guerrilla combat, and nursing, fighting bravely on the Burma-Imphal front.

Therefore, the regiment was the Rani Jhansi Regiment (Option B).

Leadership of the 1857 Revolt in Bareilly, Rohilkhand (Uttar Pradesh):

• Following the outbreak of the rebellion at Meerut and Delhi, Khan Bahadur Khan Rohilla, the aged grandson of the last independent Rohilla chieftain Hafiz Rahmat Khan, assumed leadership of the 1857 Revolt in Bareilly (Rohilkhand) in May 1857.
• Proclaiming himself Nawab Nazim/Viceroy on behalf of Mughal Emperor Bahadur Shah Zafar, Khan Bahadur Khan established an efficient, united civil administration with Hindu and Muslim ministers (including Shobha Ram as his Dewan) and organized stiff military resistance against the British until Bareilly was recaptured by Sir Colin Campbell in May 1858.
• (Begum Hazrat Mahal led in Lucknow, Nana Saheb and Tatya Tope led in Kanpur, and Kunwar Singh led in Jagdishpur, Bihar).

Therefore, the leader in Bareilly was Khan Bahadur Khan (Option B).

Chronological order of Modern Indian Freedom Movement events:

1. Home Rule Movement: Launched in April 1916 by Bal Gangadhar Tilak at Belgaum and in September 1916 by Annie Besant at Madras.
2. Jallianwala Bagh Massacre: Took place on Baisakhi day, 13 April 1919 in Amritsar, Punjab.
3. Khilafat Movement: Formally launched with the All India Khilafat Conference in Delhi in November 1919 and the nationwide Khilafat Day on 17 October 1919 (merged into Non-Cooperation in August 1920).
4. Moplah (Mappila) Revolt: Outbroke in August 1921 in the Malabar district of Kerala as an agrarian peasant rebellion of Muslim tenants against Hindu jenmis (landlords) and British colonial forces.

Therefore, the event that took place LAST in chronological order was the Moplah Revolt (1921, Option D).

Women freedom fighters and their association with the Quit India Movement (1942):

• Aruna Asaf Ali: Famous as the 'Heroine of the 1942 Movement', she hoisted the Indian National Congress tricolour at the Gowalia Tank Maidan in Bombay on 9 August 1942 and operated the underground resistance.
• Matangini Hazra: 73-year-old peasant freedom fighter ('Gandhi Buri') who was shot dead by British police while leading a Quit India march holding the national flag at Tamluk, Midnapore (Bengal) on 29 September 1942.
• Kanaklata Barua: 17-year-old martyr of Assam ('Birbala') who was shot dead while trying to hoist the tricolour at the Gohpur police station during the Quit India Movement on 20 September 1942.
• Shanti Ghosh: A militant Bengali revolutionary who, along with Suniti Chaudhary, shot dead the tyrannical British District Magistrate C.G.B. Stevens at Comilla on 14 December 1931 during the revolutionary terror phase. She was NOT associated with the 1942 Quit India Movement.

Therefore, the woman fighter NOT associated with Quit India is Shanti Ghosh (Option D).

Evaluation of Indian Peninsular Rivers and their Tributaries:

• Manjra — Godavari: Correctly matched (Manjra/Manjira is a major right-bank tributary of the Godavari).
• Hemavathi — Kaveri: Correctly matched (Hemavati is an important left-bank tributary of the Kaveri originating in Karnataka).
• Malaprabha — Krishna: Correctly matched (Malaprabha, along with Ghataprabha and Tungabhadra, is a right-bank tributary of the Krishna).
• Pranhita — Mahanadi: INCORRECTLY MATCHED. Pranhita is the largest tributary of the GODAVARI River (formed by the confluence of the Penganga, Wardha, and Wainganga rivers, conveying about 34% of Godavari's total discharge), having NO connection with the Mahanadi. (Major tributaries of the Mahanadi are Seonath, Hasdeo, Mand, Ib, Jonk, Ong, and Tel).

Therefore, the pair not correctly matched is Pranhita — Mahanadi (Option D).

The Panch Prayags (Sacred Confluences) along the Alaknanda River in Uttarakhand:

• The five holy river confluences in descending order along the Alaknanda:

1. Vishnuprayag: Confluence of the Alaknanda and Dhauliganga.
2. Nandaprayag: Confluence of the Alaknanda and Nandakini.
3. Karnaprayag: Confluence of the Alaknanda and Pindar River.
4. Rudraprayag: Confluence of the Alaknanda and Mandakini (Kali Ganga).
5. Devprayag: The ultimate holy confluence of the Alaknanda and Bhagirathi, downstream of which the unified mighty river is formally called the GANGA.

Therefore, the confluence of the Alaknanda and the Bhagirathi is at Devprayag (Option D).

Analysis of Laterite Soils:

1. Statement 1 is correct: Laterite soils develop in tropical and subtropical regions characterized by high temperatures and alternating wet and dry seasons with heavy rainfall. Intense tropical rains cause heavy leaching (removal of silica and lime), leaving behind a residue of hydrated oxides of iron and aluminium.
2. Statement 2 is incorrect: Because silica is leached away, laterite soils are rich in iron oxide and aluminium compounds (giving them their characteristic red/yellow color). They are actually poor in nitrogen, phosphate, potassium, lime, and humus.

Therefore, only Statement 1 is correct (Option A).

The Ozone layer (Ozonosphere) is located primarily in the Stratosphere, between approximately 15 km and 35 km above the Earth's surface.

• It absorbs 97% to 99% of the Sun's harmful, medium-frequency ultraviolet light (UV-B rays between 200 nm and 315 nm), protecting living organisms on Earth from cellular damage, skin cancers, and cataracts.
• While 'good ozone' resides in the stratosphere, ozone found in the troposphere is a hazardous ground-level secondary pollutant and a component of photochemical smog.

Matching chief Indian rivers with their exact places of origin:

| River | Place of Origin |

| :--- | :--- |

| A. Yamuna | 4. Yamunotri Glacier (Bandarpunch peaks, Uttarakhand) |

| B. Krishna | 3. Mahabaleshwar (Western Ghats, Maharashtra) |

| C. Godavari | 2. Trimbakeshwar / Nasik (Western Ghats, Maharashtra) |

| D. Mahanadi | 1. Sihawa Mountain (Dhamtari, Chhattisgarh) |

Hence, the correct matching code is A-4, B-3, C-2, D-1 (Option A).

1. Assertion (A) is true: The Coromandel (Tamil Nadu) coast remains dry and receives very little rain during the South-West monsoon season (June to September). It receives the bulk of its rainfall during the retreating / North-East monsoon season (October to December).
2. Reason (R) is true and is the correct explanation: The Tamil Nadu coast remains dry because:

• It is aligned parallel to the Bay of Bengal branch of the SW monsoon, meaning moisture-laden winds blow past without orographic barrier to cause condensation.
• It lies in the rain-shadow area (leeward side) of the Western Ghats for the Arabian Sea branch of the SW monsoon.

Thus, both (A) and (R) are true, and (R) correctly explains (A) (Option D).

Evaluation of River Confluences in Uttar Pradesh:

1. Statement 1 is correct: The Ramganga River originates in the Doodhatoli ranges of Pauri Garhwal (Uttarakhand), enters UP in Bijnor, flows past Moradabad and Bareilly, and joins the Ganga River near Kannauj.
2. Statement 2 is incorrect: The Betwa River originates in the Vindhya Range in Raisen (Madhya Pradesh), flows through Bundelkhand (Lalitpur, Jhansi, Jalaun), and joins the Yamuna River near Hamirpur, NOT near Prayagraj. (Yamuna herself joins Ganga at Prayagraj).

Therefore, only Statement 1 is correct (Option A).

Chandraprabha Wildlife Sanctuary is situated in the Chandauli district of Uttar Pradesh (established in 1957).

• It was established primarily to conserve the Asiatic lion (a lion reintroduction project was carried out here in 1957 with a pair of Asiatic lions from Gir, Gujarat, though it later died out).
• It is famous for scenic waterfalls like Rajdari and Devdari, and covers an area of approximately 78 sq km in the Vindhyan plateau region.

Evaluation of Himalayan Mountain Passes and their States/UTs:

• A. Aghil Pass: Located in the Karakoram Range in Ladakh (UT), connecting Ladakh with Xinjiang (China) — NOT Arunachal Pradesh.
• B. Diphu Pass: Located on the tri-junction of India, China, and Myanmar in Arunachal Pradesh — NOT Ladakh.
• C. Niti Pass: Located in Chamoli district of Uttarakhand, connecting Uttarakhand with Tibet at an elevation of 5,068 m — Correctly Matched.
• D. Mana Pass (Dungri La): Located in Chamoli district of Uttarakhand, connecting India and Tibet — NOT Himachal Pradesh.

Therefore, Option C is correctly matched.

Energy Generation Facilities:

1. Shivanasamudra: Located on the Kaveri (Cauvery) River in Mandya/Chamarajanagar district, Karnataka. In 1902, the Shivanasamudra Hydroelectric Project was commissioned (one of the earliest major hydroelectric power stations in Asia and India, which supplied power to the Kolar Gold Fields).
2. Kalpakkam (Madras Atomic Power Station - MAPS): Located in Chengalpattu district, Tamil Nadu. It is famous for India's indigenous Nuclear Power generation, hosting pressurized heavy water reactors (PHWR) and the Prototype Fast Breeder Reactor (PFBR).

Therefore, they are respectively important for Hydel Power and Nuclear Energy (Option A).

Analysis of Forest Data for Uttar Pradesh (Based on ISFR 2021):

1. Statement 1 is incorrect: According to the India State of Forest Report (ISFR) 2021, the Forest Cover of Uttar Pradesh is 14,817.89 sq km, which is only 6.15% of the state's total geographical area (or 7.22% including Tree Cover of 3.08% totaling ~9.23%). The Recorded Forest Area (RFA) is 6.88% (16,582 sq km). It is nowhere near 12.8%.
2. Statement 2 is incorrect: It is factually wrong to say Jaunpur, Ghazipur, and Ballia have 'no forest land' (0 sq km). While they have very low forest cover, ISFR 2021 records: Jaunpur has 15.65 sq km, Ghazipur has 18.06 sq km, and Ballia has 20.89 sq km of forest cover. (Bhadohi has the lowest percentage at 0.37%, followed by Mainpuri and Deoria).

Therefore, Neither 1 nor 2 is correct (Option D).

Examination of Seaports and Countries:

• Rotterdam — Netherlands: One of the busiest ports in the world and Europe's largest seaport, located at the Rhine-Meuse-Scheldt delta (Correct).
• Igarka — China (Incorrect): Igarka is in Russia (Krasnoyarsk Krai, Siberia), situated on the lower Yenisey River within the Arctic Circle. It is an important Arctic port for timber export.
• Montevideo — Uruguay: Capital and chief port city of Uruguay on the northeastern bank of the Río de la Plata (Correct).
• Jakarta — Indonesia: Major port and capital city of Indonesia on Java island (Tanjung Priok port) (Correct).

Thus, Igarka — China is not correctly matched (Option B).

Evaluation of Oceanographic Statements:

• A is false: The Benguela Current is a cold ocean current of the South Atlantic Ocean (flowing northwards along the western coast of Southern Africa), NOT the Pacific Ocean.
• B is false: When the Sun, Earth, and Moon are in a straight line (Syzygy - conjunction during New Moon or opposition during Full Moon), their gravitational forces combine to create the highest tides, called Spring Tides (not small/neap tides).
• C is true: Ocean surface salinity is highest in the subtropical belts around the Tropics of Cancer and Capricorn (20° to 30° latitudes). This is because these regions experience clear skies, intense solar radiation causing extremely high rates of evaporation, and descending air masses with negligible precipitation.
• D is false: Tides occur at any given place twice daily at intervals of approximately 12 hours and 26 minutes (due to the lunar day of 24 hours 50 minutes), not 'exactly 12 hours 30 minutes'.

Therefore, Statement C is true (Option C).

The Rio Grande (known in Mexico as the Río Bravo del Norte) forms a 2,019 km (1,255 mile) natural boundary between the United States (Texas) and Mexico (states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas).

• It originates in the San Juan Mountains of Colorado and empties into the Gulf of Mexico.
• Under the 1848 Treaty of Guadalupe Hidalgo, the Rio Grande was formally recognized as the international border between the two countries.

Arranging the Deserts in Increasing Order of Size (Smallest to Largest):

1. (I) Great Sandy Desert (Australia): Area is approximately 285,000 sq km (Smallest among the four).
2. (IV) Gobi Desert (Mongolia/China): Area is approximately 1,295,000 sq km.
3. (II) Arabian Desert (Western Asia): Area is approximately 2,330,000 sq km.
4. (III) Sahara Desert (North Africa): Area is approximately 9,200,000 sq km (Largest subtropical desert in the world).

Ascending Order (Smallest to Largest): I → IV → II → III (Option C).

Agricultural Colonial History of the Philippines:

• During Spanish colonial rule (1565–1898), the Spanish colonial administration and Catholic monastic orders introduced large-scale commercial hacienda agriculture, laying the foundation for sugarcane and coconut plantations across Luzon and the Visayas (especially Negros Island).
• Following the Spanish-American War in 1898, the United States modernized the agricultural infrastructure, instituted tariff-free trade quotas (Payne-Aldrich Tariff Act of 1909), and industrialized the milling and export of copra (coconut) and centrifugal sugar.

Therefore, the credit for developing coconut and sugarcane agriculture goes to the Spanish and Americans (Option D).

Matching African Mountain Peaks with their Countries:

| Mountain Peak | Country |

| :--- | :--- |

| A. Kilimanjaro | 3. Tanzania (Highest peak in Africa, 5,895 m, dormant volcano) |

| B. Toubkal | 1. Morocco (Highest peak in Atlas Mountains & North Africa, 4,167 m) |

| C. Stanley (Mount Ngaliema) | 4. Uganda / DR Congo border (Rwenzori Mountains, 5,109 m) |

| D. Hoggar (Ahaggar) | 2. Algeria (Highland plateau in central Sahara, Mount Tahat 2,908 m) |

Hence, the correct matching code is A-3, B-1, C-4, D-2 (Option B).

Evaluation of World Lakes and their Countries:

• Lake Baikal — Russia: World's deepest (1,642 m) and oldest freshwater lake, located in Siberia, Russia (Correct).
• Lake Michigan — United States of America: The only Great Lake located entirely within the US borders (Correct).
• Lake Onega — Canada (INCORRECT): Lake Onega is in northwestern Russia (Republic of Karelia, Leningrad Oblast, Vologda Oblast). It is the second-largest lake in Europe after Lake Ladoga (both are in Russia). It is NOT in Canada.
• Lake Maracaibo — Venezuela: Large brackish tidal bay/lake in Venezuela, famous for extensive petroleum deposits and Catatumbo lightning (Correct).

Therefore, Lake Onega — Canada is not correctly matched (Option C).

Analysis of El Niño Phenomenon:

1. Statement 1 is correct: El Niño involves the development of an abnormal warm ocean surface current off the coast of Peru and Ecuador in the eastern tropical Pacific Ocean, replacing the normally cold Peruvian (Humboldt) Current around Christmas time.
2. Statement 2 is incorrect: While the warm current does increase surface water temperatures along the Peruvian coast (sometimes by up to 8-10°C), this warming suppresses the normal upwelling of cold, nutrient-rich deep water. Without nutrients (nitrates and phosphates), phytoplankton production collapses, leading to a catastrophic decrease (decline) in the fish population and plankton, devastating the Peruvian anchovy fishery and guano birds.

Therefore, only Statement 1 is correct (Option A).

Deflection of Planetary Winds:

• The deflection of moving air (winds) to the right in the Northern Hemisphere and to the left in the Southern Hemisphere is caused by the Coriolis Force (formulated as Ferrel's Law).
• The Coriolis force is an apparent or inertial force that acts on moving objects in a rotating frame of reference, produced by the rotation of the Earth on its axis from west to east.
• It is zero at the Equator and increases towards the poles directly proportional to the sine of the latitude (2\Omega v \sin\phi).

Identification of Noble Gases:

• Noble Gases (Inert Gases) occupy Group 18 of the Periodic Table, characterized by completely filled outer valence electron shells (ns² np⁶, helium 1s²), making them chemically stable and unreactive under standard conditions. They are:
• Helium (He, Z=2)
• Neon (Ne, Z=10)
• Argon (Ar, Z=18)
• Krypton (Kr, Z=36)
• Xenon (Xe, Z=54)
• Radon (Rn, Z=86)
• Oganesson (Og, Z=118)
• Actinium (Ac, atomic number 89) is a radioactive silvery-white metallic element belonging to the Actinide series (f-block/Group 3), NOT a noble gas.

Therefore, Actinium is not a noble gas (Option D).

Endocrine Function of Pancreas (Islets of Langerhans):

• The endocrine tissue of the pancreas consists of clusters of cells called the Islets of Langerhans, which contain distinct hormone-secreting cell types:

1. Beta ($\beta$) cells (~70% of islet cells): Secrete Insulin, which lowers blood glucose levels by promoting glucose uptake into muscle, liver, and adipose cells and stimulating glycogenesis.
2. Alpha ($\alpha$) cells (~20%): Secrete Glucagon, which raises blood glucose levels through glycogenolysis.
3. Delta ($\delta$) cells: Secrete Somatostatin (inhibits insulin and glucagon release).
4. PP / F cells: Secrete pancreatic polypeptide.

• Adrenalin is secreted by the adrenal medulla; Aldosterone is secreted by the adrenal cortex.

Therefore, Beta cells secrete Insulin (Option B).

Vaccine Types and Diphtheria Protection:

• Diphtheria is a serious bacterial infection caused by Corynebacterium diphtheriae, which produces a dangerous exotoxin causing pseudomembrane formation in the respiratory tract and potential cardiac/neural toxicity.
• The vaccine protecting against diphtheria is a Toxoid vaccine.
• A toxoid is an inactivated bacterial exotoxin that has been treated (typically with formaldehyde) so that its toxicity is neutralized, but its immunogenicity is fully preserved to stimulate the production of protective neutralizing antibodies (antitoxins).
• Diphtheria toxoid is administered as part of the DPT / Pentavalent vaccine (Diphtheria toxoid, Pertussis whole-cell/acellular, and Tetanus toxoid).

Therefore, the vaccine type is Toxoid (Option A).

mRNA Vaccines for COVID-19:

• Moderna (mRNA-1273 / Spikevax) is an mRNA vaccine developed by Moderna in collaboration with the US National Institute of Allergy and Infectious Diseases (NIAID).
• It works by delivering synthetic messenger RNA encapsulated in lipid nanoparticles (LNPs) that instructs the host cells to produce the harmless Spike (S) protein of SARS-CoV-2, thereby triggering a robust immune response and antibody production.
• Comparison of the other options:
• Sinovac (CoronaVac): Inactivated whole-virus vaccine (China)
• Sputnik V: Adenoviral vector-based vaccine (Gamaleya Institute, Russia)
• Novavax (Covovax / NVX-CoV2373): Protein subunit vaccine

Therefore, Moderna is the mRNA vaccine (Option B).

Key Drivers of Biodiversity Loss:

• According to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and the Convention on Biological Diversity (CBD), the destruction, degradation, and fragmentation of natural habitats is the single most important and primary factor causing global biodiversity loss and species extinction.
• Forest clearance for agriculture, urbanization, infrastructure, and mining directly deprives wild species of their feeding, breeding, and sheltering grounds, triggering the fastest population collapses worldwide.
• The four major causes of biodiversity loss are famously termed 'The Evil Quartet':

1. Habitat loss and fragmentation (most important)
2. Over-exploitation
3. Alien species invasion
4. Co-extinctions

Therefore, destruction of natural habitat is the correct answer (Option C).

Vascular Plant Tissues Function:

• Xylem is the complex vascular tissue in plants responsible for the unidirectional transport of water and dissolved mineral nutrients from the roots upwards to the stems and leaves.
• It consists of four elements: tracheids, vessels, xylem parenchyma, and xylem fibres (mostly dead cells at maturity except parenchyma).
• In contrast, Phloem is responsible for the multidirectional translocation of soluble organic compounds (food/photosynthates, mainly sucrose and amino acids) from source (leaves) to sinks (roots, fruits).

Therefore, Xylem is responsible for transporting Water (Option A).

Classification of Energy Resources:

• Non-conventional energy sources (also known as alternative or renewable energy sources) are those energy sources that are Renewable, naturally replenished on a human timescale, virtually inexhaustible, and cause little to no environmental pollution.
• Examples include Solar energy, Wind energy, Hydroelectric power, Biomass energy, Geothermal energy, and Tidal/Ocean energy.
• In contrast, Conventional energy sources are non-renewable fossil fuels (coal, petroleum, natural gas) that have been traditionally used for generations and are finite in reserve.

Therefore, non-conventional energy sources are Renewable (Option B).

Biological Oxygen Demand (BOD):

• Biochemical / Biological Oxygen Demand (BOD) is the amount of dissolved oxygen (DO) required by aerobic micro-organisms to decompose the biodegradable organic material present in a given sample of water at a specified temperature (usually 20°C) over a 5-day incubation period (BOD5).
• High BOD indicates that a large quantity of organic matter is present, leading to severe oxygen depletion that threatens aquatic life.
• Therefore, BOD is universally used as a standard regulatory criteria for Pollution assay in aquatic ecosystems (Option A).

Aquatic Biofertilizer in Paddy Fields:

• Azolla is a genus of small, free-floating freshwater aquatic ferns.
• In water-logged rice (paddy) fields, Azolla maintains an obligate endosymbiotic relationship with the nitrogen-fixing cyanobacterium (blue-green alga) Anabaena azollae, which resides within cavities in the dorsal leaves of the fern.
• The cyanobacterium fixes atmospheric nitrogen into ammonium, providing 40–60 kg N/ha to the standing rice crop while suppressing weeds and reducing evaporation.

Therefore, Azolla is the biofertilizer commonly used in water-logged rice fields (Option B).

Laughing Gas Chemical Identity:

• Nitrous Oxide ($N_2O$), also known as dinitrogen monoxide, is popularly called Laughing Gas.
• Discovered by Joseph Priestley in 1772 and popularized by Humphry Davy, when inhaled in small doses it produces mild euphoria, dissociation, and spontaneous laughter due to its analgesic and mild anesthetic properties.
• It is commonly used in dentistry and minor surgery as an anesthetic and analgesic agent, and in racing engines as a fuel oxidizer.

Therefore, Nitrous Oxide is known as laughing gas (Option B).

Nutritional/Chemical Value of Seaweeds:

• Seaweeds (marine macroalgae, especially brown algae like Laminaria, Fucus, and Sargassum, and red algae) have a unique biological capacity to selectively concentrate halides from seawater, making them the richest natural dietary and commercial source of Iodine.
• Historically, elemental iodine was first discovered and extracted by Bernard Courtois in 1811 by burning seaweed (kelp) ash with sulphuric acid.
• Regular dietary consumption of edible seaweed (such as nori, kombu, and wakame) helps prevent iodine deficiency disorders like goitre.

Therefore, seaweeds are an important source of Iodine (Option A).

Insectivorous (Carnivorous) Plants:

• Nepenthes (commonly known as tropical Pitcher Plant) is an insectivorous plant.
• Insectivorous plants grow in waterlogged, acidic bogs and soils that are severely deficient in nitrogen. To fulfill their nitrogen requirement, they have evolved modified leaves that form deep, fluid-filled pitchers with slippery rims and digestive enzymes that trap, drown, and digest insects.
• In India, Nepenthes khasiana is endemic to the Khasi, Jaintia, and Garo hills of Meghalaya.
• The other plants listed (Nyctanthes - Night-flowering Jasmine/Parijat, Nelumbo - Lotus, Nicotiana - Tobacco) are standard autotrophic flowering plants.

Therefore, Nepenthes is the insectivorous plant (Option D).

Anatomy of the Human Heart:

• The Human heart is a muscular organ composed of four chambers:

1. Right Atrium: Receives deoxygenated blood from the body tissues via the superior and inferior vena cava.
2. Right Ventricle: Pumps deoxygenated blood through the pulmonary artery to the lungs for oxygenation.
3. Left Atrium: Receives oxygenated blood returning from the lungs via the pulmonary veins.
4. Left Ventricle: Thick muscular chamber that pumps oxygenated blood under high pressure into the aorta to supply the entire systemic circulation.

• This four-chambered design completely separates oxygenated and deoxygenated blood, ensuring high metabolic efficiency (double circulation).

Therefore, the human heart has four chambers (Option A).

India's Rank in Greenhouse Gas (GHG) Emissions (CCPI 2023):

• In the Climate Change Performance Index (CCPI 2023) published by Germanwatch, NewClimate Institute, and Climate Action Network in November 2022 (evaluating 2022 performance):
• India was ranked 8th overall among all assessed countries.
• In the specific component category of 'Greenhouse Gas (GHG) Emissions', India was ranked 9th in the world, earning a 'High' rating due to its relatively low per-capita emissions.

Therefore, India's rank was 9th (Option A).

Concept of Watershed:

• A Watershed (also called a drainage basin or catchment area) is defined in hydrology and physical geography as a discrete topographically delineated geographical unit that collects, stores, and channels surface runoff and groundwater, releasing water through a single common outlet into a stream, river, lake, or wetland.
• Watershed management encompasses soil and water conservation, groundwater recharge, and vegetative cover restoration (e.g., Watershed Development Programme / PMKSY Watershed component).

Therefore, a geographical unit that collects, stores and releases water is called a Watershed (Option A).

Water (Prevention and Control of Pollution) Act:

• The Water (Prevention and Control of Pollution) Act was enacted by the Indian Parliament in 1974.
• It was India's first major comprehensive environmental legislation, enacted under Article 252 of the Constitution following the 1972 Stockholm UN Conference on Human Environment.
• The Act established statutory bodies for pollution regulation:
• Central Board for the Prevention and Control of Water Pollution (later renamed Central Pollution Control Board - CPCB)
• State Pollution Control Boards (SPCBs)
• It empowers boards to set water quality standards, inspect industrial units, and prohibit discharge of polluting matter into water bodies.

Therefore, the Act was enacted in 1974 (Option A).

Classification of Aquatic Ecosystems (Lotic vs Lentic):

• Freshwater aquatic ecosystems are categorized based on whether the water is moving or stagnant:

1. Lotic Ecosystems (Moving/Flowing water): The water is in continuous unidirectional flow. Prime examples include Rivers, streams, brooks, and springs.
2. Lentic Ecosystems (Still/Standing water): The water is calm and motionless. Prime examples include Ponds, lakes, swamps, bogs, and marshes.

Therefore, an example of a lotic ecosystem is Rivers (Option C).

National Centre for Marine Biodiversity (NCMB):

• India's first National Centre for Marine Biodiversity (NCMB) is located at Jamnagar, Gujarat.
• It was established as a public-private partnership (PPP) between the Ministry of Environment, Forest and Climate Change (MoEFCC) and Reliance Industries Limited near the Marine National Park in the Gulf of Kutch.
• Its primary mandate is to conduct advanced research, safeguard marine flora and fauna (coral reefs, mangroves, sea cows/dugongs), and build national capacity in coastal and marine biodiversity conservation.

Chemical Composition of Natural Silk:

• Natural silk is an animal protein fibre produced by the larvae of silkworms (primarily Bombyx mori feeding on mulberry leaves).
• Because silk is a fibrous protein, its fundamental building blocks are amino acids (mainly glycine, alanine, and serine) linked by peptide bonds (-CO-NH-).
• All amino acids contain amine groups (-NH₂), making Nitrogen an essential chemical constituent of silk (~18-19% by mass).
• Silk contains two key proteins: Fibroin (the structural core, ~70-80%) and Sericin (the gummy coating, ~20-30%).

Therefore, a primary constituent of natural silk is Nitrogen (Option B).

Adaptation Terminology in Ecology:

• Xerocoles (or Xericoles) are animals adapted to live in deserts and arid/dry environments.
• They exhibit specialized behavioral and physiological adaptations to conserve water, such as nocturnal activity, concentrated urine/dry feces (e.g., kangaroo rat, camel), burrowing habits, and thick impervious integuments.
• Comparison of other ecological terms:
• Arboreal animals: Adapted to live in trees (e.g., monkeys, squirrels).
• Terrestrial animals: Animals that live predominantly on land.
• Fossorial animals: Animals adapted to digging and living underground in burrows (e.g., moles, earthworms).

Therefore, desert dwelling animals are called Xericoles animals (Option D).

Matching Human Diseases with their Causative Agents:

| Disease | Causative Agent (Pathogen) |

| :--- | :--- |

| A. Peptic ulcers | 4. Bacteria (Helicobacter pylori, discovered by Robin Warren and Barry Marshall) |

| B. Dengue | 1. Virus (Dengue virus / Flavivirus, transmitted by Aedes aegypti mosquito) |

| C. Elephantiasis (Elephant Foot / Filariasis) | 3. Worm (Wuchereria bancrofti / Brugia malayi, filarial nematodes) |

| D. Malaria | 2. Protozoa (Plasmodium vivax/falciparum, transmitted by female Anopheles mosquito) |

Hence, the correct matching code is A-4, B-1, C-3, D-2 (Option B).

Concept of Trophic Levels in Ecosystems:

• In ecology, a Trophic Level is the hierarchical feeding position that an organism occupies in a food chain or ecological food web.
• Trophic levels are formed by organisms linked in a food chain:
• First Trophic Level ($T_1$): Primary producers (green plants, autotrophs).
• Second Trophic Level ($T_2$): Primary consumers (herbivores).
• Third Trophic Level ($T_3$): Secondary consumers (carnivores).
• Fourth Trophic Level ($T_4$): Tertiary consumers (top carnivores / apex predators).
• Because energy transfers sequentially through these nutritional steps following Lindeman's 10% Law, trophic levels necessarily comprise all organisms connected in the food chain (plants, herbivores, carnivores, and decomposers).

Therefore, trophic levels are formed by Organisms linked in food chain (Option A).

Biodiversity Conservation Strategies (In-Situ vs Ex-Situ):

• In-situ Conservation (On-site conservation) means the conservation of genetic resources, endangered species, and ecosystems in their natural habitats and natural surroundings.
• Protected areas such as National Parks, Wildlife Sanctuaries, Biosphere Reserves, and Sacred Groves are the primary mechanisms for in-situ conservation, where populations are preserved within the natural evolutionary dynamic of their wild habitat.
• In contrast, Ex-situ Conservation (Off-site conservation) involves protecting species outside their natural habitats (e.g., Botanical Gardens, Zoos, Seed Banks, Gene Banks, Cryopreservation).

Therefore, in National Parks, genetic diversity is maintained by In-situ conservation (Option A).

Hangul Deer Habitat in India:

• The *Hangul (also known as the Kashmir Stag, Cervus hanglu hanglu)* is a critically endangered subspecies of Central Asian red deer native to India.
• It is found exclusively in Jammu and Kashmir, with its last viable wild stronghold residing in Dachigam National Park near Srinagar, as well as small relict pockets in the Overa-Aru Wildlife Sanctuary in the Kashmir Valley.
• It is the state animal of the erstwhile state (now UT) of Jammu and Kashmir and is protected under Schedule I of the Wildlife Protection Act, 1972.
