Correct Option: B

Birsa Munda was a tribal leader and a folk hero, belonging to the Munda tribe who was behind the millenarian movement that rose in the tribal belt of Jharkhand during the British raj, in the late 19th century. To the twin challenges of agrarian breakdown and culture change, Birsa along with the Munda responded through a series of revolts and uprisings under his leadership. The movement sought to assert rights of the Mundas as the real proprietors of the soil, and the expulsion of middlemen and the British.
