The commonly used answer in exam answer keys is 324 islands, an approximate figure.
The Andaman and Nicobar Islands form a group of islands in the Bay of Bengal, made up of the Andaman group in the north and the Nicobar group in the south. Different sources give slightly different counts of islands, islets, and rocky outcrops, which is why this number can vary across textbooks and answer keys.
Only a small fraction of these islands are actually inhabited, while the rest remain uninhabited or are protected as forest and tribal reserves.
