The correct answer to this question is C, Assam. The revolt of Songram Sangma was one of the major revolts against the British. The other major revolt was the forest Satyagraha in the Central Provinces, which occured in 1930. These revolts occured because of the exploration of British, which deprived the tribes of their forest rights, which they were used to.
The revolts greatly affected the tribes because they were exploited by the traders and the lenders of money that invaded their land. Assam, where the revolt occured, is a state in India. It has many things it is known for, including its wildlife and tea.
C is the correct answer. The revolt of Songram Sangma in Assam was the result of the invasion of the British to the tribal people of India. The tribal people, of course, were scattered in the deep forests and the British forced them all to live in a small land to control them better. The tribal was not also allowed to cultivate and hunt in the forests and like anyone who has stolen their homes and livelihoods from them did not like it.
They revolted in 1906 as a protest in these British laws. These laws greatly affected the lives of the tribal that they needed to pay tribute to the officers in an exchange of cheap labor. The tribals were forced to leave their land and work in mines and plantations instead of living peacefully in the forest.
