Match List-I with List-II and select the correct answer from the code given below: List-I A) Golden Triangle B) Bermuda Triangle C) Rice bowl of Far East D) Red Basin List-II 1) Myanmar 2) China 3) Thailand 4) North Atlantic Ocean

The correct answer is D: A-1, B-4, C-3, D-2.

• Golden Triangle (A-1): The region where Myanmar, Laos and Thailand meet at the confluence of the Ruak and Mekong rivers. It was long notorious for opium and heroin production and trafficking.
• Bermuda Triangle (B-4): A stretch of the North Atlantic Ocean between Bermuda, Miami and Puerto Rico, known for unexplained ship and aircraft disappearances.
• Rice bowl of Far East (C-3): Thailand is one of the world's largest rice exporters, so it fits this description best among the options.
• Red Basin (D-2): The Sichuan Basin in China, named for its red sandstone and mudstone.

Option A places Thailand against the Golden Triangle and China against the Bermuda Triangle, which is wrong. Option B links the Golden Triangle with China, and option C links it with the North Atlantic. Both fail on the first pair.

The core concept is geographical identification of named regions. For Mains, the Golden Triangle connects to the Mekong sub-regional cooperation and to the drug trafficking challenge on India's eastern frontier, which matters under the Act East Policy.

Trap: Candidates often assign Myanmar to the rice bowl clue because Burma was historically a major rice exporter. Match the options first, and check which pairs are actually possible.
