The correct option is C Assam Gana Parishad came to power in 1984.
The AASU and the Assam Gana Sangram Parishad organised themselves as a regional political party called Assam Gana Parishad (AGP). It came to power in 1985 with the promise of resolving the foreign national problem. Bodos, Khasis, Mizos, and Karbis demanded autonomous status, and wanted to drive the other communities out of their areas. This caused the forcible eviction of minority tribal communities.
