The correct answer is: b) Ceasefire between the Indian government and Naga groups.
The 16-Point Agreement was signed on 29 July 1960 between the Government of India and the Naga National Council (NNC). The agreement was an attempt to resolve the Naga conflict, which had been ongoing since 1947. The agreement led to a ceasefire between the Indian government and the NNC, and it also established a regional council for the Naga Hills.
The 16-Point Agreement was not without its critics. Some people felt that it gave too much power to the NNC, and that it did not adequately address the concerns of the Naga people. However, the agreement did succeed in bringing an end to the violence, and it provided a framework for future negotiations between the Indian government and the Naga people.
The other options are incorrect because:
- Option (a) is incorrect because the state of Nagaland was not created until 1963.
- Option (c) is incorrect because the 16-Point Agreement did not provide for constitutional safeguards for Naga customary laws.
- Option (d) is incorrect because the 16-Point Agreement did not establish a regional council for the Naga Hills.
