The origin of Lakshadweep islands is mainly linked with what?

Corals

Lakshadweep is an island group in the Arabian Sea made mainly of coral islands and atolls. Corals are tiny marine organisms that build calcium-carbonate structures in warm, shallow, clear tropical waters. Over long periods, coral growth and the accumulation of reef material can form islands or ring-shaped atolls, often around a lagoon. This origin distinguishes Lakshadweep from islands formed mainly by rivers, glaciers, or volcanic cones.

Option C is correct because Lakshadweep is classically described in school geography as a coral island group. River deposition generally creates deltas or sedimentary islands near river mouths, while glaciers form or modify islands in cold regions. Volcanoes can create islands elsewhere, but volcanic origin is not the principal identification used for Lakshadweep in this question. The key association to remember is Lakshadweep and coral reefs.
