From which Island in India the coral originated?

Question

Accepted Answer

The correct option is 2:
Lakshadweep is a group of islands in the Arabian Sea known for its extensive coral reefs. These islands are primarily atolls, which are ring-shaped coral reefs that enclose a lagoon. The formation of these islands is intrinsically linked to the growth and accumulation of corals over thousands of years. Coral polyps, tiny marine invertebrates, secrete calcium carbonate to form hard exoskeletons, which collectively build vast reef structures. The favorable warm, clear, and shallow waters of the Arabian Sea provide an ideal environment for coral growth, making Lakshadweep a prime example of coral-originated islands in India.

The incorrect option is 1: Andaman
The Andaman Islands, while also home to coral reefs, are primarily tectonic in origin, formed by the collision of the Indian Plate and the Burmese Plate. While coral growth and erosion have played a significant role in refining their coastlines and enriching marine biodiversity, their fundamental geological origin is not solely from coral.

The incorrect option is 3: Nicobar
Similar to the Andaman Islands, the Nicobar Islands are also primarily of tectonic origin. They are part of the same island arc system formed by geological activity. Although they possess coral reefs, the islands themselves did not originate solely from coral activity.

The incorrect option is 4: None of these
This option is incorrect because Lakshadweep is indeed an island group in India where corals are the primary origin of the landmass.
