Correct Answer: Option (A) — 1 only
Concept & Option Breakdown
Standard Reference Verified• Statement 1 is correct: Barren Island, located in the Andaman Sea, is India's only confirmed active volcano. • Statement 2 is incorrect: Barren Island lies about 135–140 km northeast of Port Blair (Andaman Islands), not Great Nicobar (which is located much further south). • Statement 3 is incorrect: Barren Island erupted in 1991, 1994–95, 2005, 2008–09, and notably in 2017–2018; it has not remained inactive since 1991.
Statements 1 and 3 are in tension: if Barren Island is famously an 'active volcano', claiming it has been completely inactive for nearly three decades (since 1991) is contradictory, making statement 3 false.
