The correct answer is: B. 15th August, 1985.
The Assam Accord was a peace accord signed on 15 August 1985 between the Government of India and the All Assam Students Union (AASU). The accord was signed to end the Assam Agitation, which had been going on since 1979. The accord led to the deportation of over 2 million illegal immigrants from Assam.
The accord was signed by the then Prime Minister of India, Rajiv Gandhi, and the AASU leader, Prafulla Kumar Mahanta. The accord had 15 points, which included the following:
- Detection and deportation of illegal immigrants from Assam.
- Identification of foreigners who had entered Assam after 25 March 1971.
- Grant of citizenship to those who had entered Assam before 25 March 1971 and had been staying there continuously.
- Special provisions for the development of Assam.
- Establishment of a tribunal to settle the claims of those who had been declared foreigners.
The Assam Accord was a landmark agreement that brought an end to the Assam Agitation. It has been credited with restoring peace and stability in Assam. However, the accord has also been criticized for not being fully implemented.
