The correct answer is C. Santhal tribe.
The Tana Bhagat Movement was a religious and political movement that took place in the Santhal Parganas region of Bihar in the late 19th century. The movement was led by the Santhal religious leader, Birsa Munda. The Santhals were a tribal people who had been oppressed by the British colonial government and by the landlords of the region. The Tana Bhagat Movement was a revolt against this oppression.
The movement began in 1895 with a series of attacks on the landlords and their property. The Santhals also refused to pay taxes to the British government. The movement was eventually suppressed by the British, but it had a significant impact on the Santhal people and on the history of India.
The other options are incorrect because they are not the tribes that participated in the Tana Bhagat Movement. The Ho tribe is a tribal people who live in the Jharkhand state of India. The Munda tribe is a tribal people who live in the Jharkhand and Orissa states of India. The Oraon tribe is a tribal people who live in the Jharkhand, Bihar, and Chhattisgarh states of India.
