The correct answer is (b), Jarawa. The Jarawa are an indigenous people of the Andaman Islands in the Bay of Bengal. They are one of the Andaman Islanders, a group of several indigenous peoples who live on the Andaman and Nicobar Islands. The Jarawa are hunter-gatherers and live in small bands. They are known for their isolation from the outside world and their resistance to contact with outsiders. In recent years, the Jarawa have been increasingly affected by contact with outsiders, including the Indian government, which has built roads and settlements on their land. The Jarawa are facing a number of threats, including loss of land, hunting, and disease. The Indian government has taken some steps to protect the Jarawa, but they remain at risk.
