The correct answer is D) Andaman and Nicobar Islands. The Shompens are a vulnerable tribal group who are indigenous to the Great Nicobar Island, which is part of the Andaman and Nicobar Islands Union Territory of India. The Shompens are one of the six Particularly Vulnerable Tribal Groups (PVTGs) residing in the Andaman and Nicobar Islands, others being Jarawas, Onge, Sentinelese, Great Andamanese, and Nicobarese (though Nicobarese is not always listed as PVTG). They inhabit the interior of Great Nicobar Island, maintaining a traditional lifestyle largely dependent on hunting and gathering.
