Explanation
Why Correct: The Toto tribe is an indigenous tribal group found exclusively in the Totopara village, located in the Alipurduar district of West Bengal, near the Bhutan border. They are one of the smallest tribal communities in India, with a population of around 1,500 people, and are classified as a Particularly Vulnerable Tribal Group (PVTG).
Distractor Analysis: Uttar Dinajpur and Malda districts are home to other tribal communities like the Rajbanshi and Santal, but not the Toto. Jhargram district is primarily associated with the Santal, Munda, and Bhumij tribes. Bankura and Jhargram districts are known for the Kurmi and Santal tribes, but the Toto are not found there.
Takeaway: The Toto language belongs to the Tibeto-Burman family, and the tribe practices a mix of animism and Hinduism, with their economy based on agriculture and the cultivation of oranges, which are a major source of income.
