Explanation:

Kharia at Jharkhand belong to the Proto-Australoid group. The Kharia in Jharkhand are said to be the descendants of Nagvanshi Raja and are divided into three major sections namely Dudh Kharia, Dhelki Kharia and Hill Kharia. The Kharia of Jharkhand are one of the most primitive tribes that chiefly depend on the resources obtained from the forests of the territory. The Hill Kharia largely depend on roots, edible herbs, leaves, fruits, seeds, flowers, honey, wax, etc; the Dhelki Kharia and Dudh Kharia depend on agriculture.
