- D.Little Andaman
Show answer
Explanation
The correct answer is B, Barren Island. This small uninhabited island in the Andaman Sea, north-east of the territorial capital, carries the only confirmed active volcano in India and in the whole of South Asia. It has erupted repeatedly in recent decades, and because the island has no permanent population the eruptions cause no loss of life.
Option A, Narcondam Island, is the most tempting wrong answer, because it too is a volcanic island of the same arc, but its volcano is dormant; Narcondam is better known as the only home of the Narcondam hornbill. Option C, Car Nicobar, is the administrative centre of the Nicobar district and lies just south of the Ten Degree Channel, but it has no volcano. Option D, Little Andaman, lies north of that channel and is known for the Onge tribe. Remember the pair: Barren is active, Narcondam is dormant.
