The correct option is B AASU
Assam faced an immigration problem from our neighbouring country, Bangladesh. The native Assamese were afraid that this would reduce the native Assamese into a minority. This strong opinion was transformed into a social movement in 1970. The All Assam Students’ Union, also known as AASU, led the agitations. It carried out a number of strikes, agitations, and marches against the central government, demanding for the removal of the migrants.
