Which option best explains the origin of the Lakshadweep Islands?

Answer and explanation

Correct answer: Atolls and reefs formed by coral organisms

Correct answer: A, atolls and reefs formed by coral organisms. Lakshadweep is an island group in the Arabian Sea known for coral islands, reefs, and atoll formations. Corals are marine organisms that build hard calcium-carbonate structures over long periods in suitable warm, shallow waters. When reef growth develops around a lagoon or an island and forms a ring-like structure, it can produce an atoll. B is wrong because Himalayan folds produced high mountain ranges in the north, not Lakshadweep’s low coral islands. C is wrong because river sediments form deltas at river mouths, whereas Lakshadweep is an offshore coral island group. D is wrong because desert dunes are wind-made landforms and do not explain these islands. Memory cue: Lakshadweep = Arabian Sea + coral reefs and atolls.
