Explanation:

• Statement 1 is correct: One of the most pristine gems of Andaman, the 354-metre high Barren Island is the only active volcano in India, having a volcanic crater that is around 2 kilometres wide. Along a chain of volcanoes from Sumatra to Myanmar, Barren Island is the sole active volcano.
• Statement 2 is correct: Most volcanoes form at the boundaries of Earth’s tectonic plates. These plates are huge slabs of the Earth’s crust and upper mantle, which fit together like pieces of a puzzle. These plates are not fixed, but are constantly moving at a very slow rate. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.
