The correct answer is: A. Tana Bhagats.
The Tana Bhagats were a group of tribal people who lived in the Ranchi and Palamu districts of Jharkhand, India. In 1928-29, they launched a no-rent campaign against the kings and the zamindars of these districts. The campaign was led by Birsa Munda, who was a Tana Bhagat leader. The Tana Bhagats were protesting against the high rents that they were being forced to pay to the kings and the zamindars. They were also protesting against the exploitation that they were facing at the hands of the landlords. The no-rent campaign was successful in forcing the kings and the zamindars to reduce the rents and to improve the conditions of the Tana Bhagats.
The Bhumij, Chero, and Hos are also tribal people who live in Jharkhand. However, they did not launch a no-rent campaign in 1928-29.
