Show answer
Answer: A. Statement 1 is correct: Barren Island in the Andaman Sea is India's only confirmed active volcano. Statement 2 is wrong: it lies about 140 km north-east of Port Blair, not east of Great Nicobar. Statement 3 is wrong: after 1991 it erupted again several times, including 2017. So only 1.
Watch for: The 1991 eruption is famous, so students assume it was the last.
Why the other options are wrong

- C. Wrong because it has erupted since 1991.
- D. Wrong because it has erupted again after 1991.
