The correct answer is: a) Greater autonomy and self-determination.
The Mizo National Front (MNF) was formed in 1966 by Laldenga, a Mizo nationalist leader. The MNF’s goal was to achieve greater autonomy for the Mizo people, who were then living in the Indian state of Assam. The MNF launched an armed struggle against the Indian government in 1967. The conflict lasted for 20 years and ended with the signing of a peace accord in 1986. The accord granted the Mizo people a large degree of autonomy, and the MNF became a political party.
The other options are incorrect. Option b) is incorrect because the MNF did not want to integrate with Assam. Option c) is incorrect because the MNF was not interested in adopting a new religious ideology. Option d) is incorrect because the MNF was not interested in economic reforms and modernization.
