Answer: C. Côte d'Ivoire and Ghana are the world's two largest cocoa producers. Côte d'Ivoire alone produces about 40% of global cocoa, and Ghana about 20% — together over 60% of world output. The cocoa belt lies in West Africa within ~10° of the equator, where high humidity and steady temperatures suit Theobroma cacao. The other options name regions that produce little or no cocoa: Algeria/Morocco (Mediterranean climate), Botswana/Namibia (semi-arid), Madagascar/Mozambique (modest cocoa production but not top-two).

Answer: A. The longest border between any two countries is between CANADA and the USA. The Canada-United States border is approximately 8,891 km long (including the Alaska-Canada border of about 2,475 km). It is the longest international land border in the world. Distractors: (B) Chile-Argentina border is about 5,300 km long (the second longest in the Americas) but shorter than Canada-USA. (C) China-India border (LAC) is about 3,488 km long. (D) Kazakhstan-Russia border is about 7,644 km, the second longest international border in the world but still less than Canada-USA.

Answer: D. The Rann of Kutch is the best example of repeated sea-level falls forming present-day marshland. The Great Rann of Kutch and Little Rann are salt marshes (about 30,000 sq km combined) in Gujarat, formed by REPEATED MARINE TRANSGRESSIONS AND REGRESSIONS over geological time. The area was a shallow sea/gulf, was uplifted with eustatic sea-level falls, and now stands as low-elevation saline marshland flooded annually during monsoon. The Rann is the world's largest salt desert. Distractors fail: (A) Bhitarkanika Mangroves (Odisha) are deltaic mangrove forests in active Brahmani-Baitarani delta, not the result of repeated sea-level falls. (B) Marakkanam Salt Pans (Tamil Nadu) are anthropogenic — man-made salt pans, not natural marshland. (C) Naupada Swamp (Andhra Pradesh) is a deltaic swamp from sediment deposition, not eustatic regression. Source: syllabus India: Physical Environment / Geological Survey of India.
