The correct option is A All Assam Students’ Union
The Assamese felt that many migrants from Bangladesh had illegally settled in their land - a strong opinion that transformed into a social movement in 1970. The All Assam Students’ Union (AASU) led the agitations.
The AASU became quite popular among the youth of Assam. It carried out several strikes, agitations, and marches against the central government, demanding the removal of outsiders.
