Consider the following statements : 1. The Barren Island volcano is an active volcano located in the Indian territory. 2. Barren Island lies about 140 km east of Great Nicobar. 3. The last time the Barren Island volcano erupted was in 1991 and it has remained inactive since then. Which of the statements given above is/are correct ?

Statement 1 is correct because Barren Island, located in the Andaman Sea, is the only confirmed active volcano in India and South Asia. Statement 3 is the most common pitfall, but it is incorrect because the volcano has erupted multiple times since 1991, including significant activity in 2017. The core concept tested is the physical geography and tectonic features of the Andaman and Nicobar Islands, specifically the volcanic arc of the Andaman Sea.
