The correct option is C Mangarh Hill
For social and moral development of the Bhils, Govind Guru established the Samp Sabha and formed Bhagat Movement to keep Bhils within the boundaries of Hinduism. When Bhils were forced to perform Begar, they began a movement. The Britishers felt that the objective of this social reform movement run by Govind Guru is the formation of a Bhil state. Govind Guru was arrested and later on released. He proceeded towards Mangarh hills and in October 1913, he gave a message and urged the Bhils to assemble on Mangarh hill.
