Answer 1

Answer:

A. 3 only

• The Andaman and Nicobar Islands are primarily of coral origin - This statement is incorrect. The Andaman and Nicobar Islands are actually of volcanic origin and are a continuation of the Arakan Yoma mountain range that extends from Myanmar. They are part of a large mountain chain that partly emerges above sea level to form these islands.

• The Lakshadweep Islands are primarily of volcanic origin - This statement is also incorrect. The Lakshadweep Islands are actually coral atolls built upon the Laccadive-Chagos submarine ridge. They are made up of coral reefs and are not volcanic in origin.

• Barren Island is an active volcanic island in the Bay of Bengal - This statement is correct. Barren Island contains the only active volcano in South Asia and is located in the Andaman Sea segment of the Bay of Bengal. It had significant eruptions in 1991 and has shown activity in more recent years as well.
