What constitutional change occurred in Jammu and Kashmir in 1965?

Designation of the head as Chief Minister

The correct answer is Option 4 - Designation of the head as Chief Minister

A change was made in 1965 by which the head of the state was designated as the Chief Minister.

During most of the period between 1953 and 1974, the Congress party exercised influence on the politics of the State. A truncated National Conference (minus Sheikh Abdullah) remained in power with the active support of Congress for some time but later it merged with the Congress. Thus, the Congress gained direct control over the government in the state and brought about the changes. In the meanwhile, there were several attempts to reach an agreement between Sheikh Abdullah and the Government of India. A change in the provision of the Constitution of Jammu and Kashmir was made in 1965 by which the Prime Minister of the state was designated as Chief Minister of the state. Accordingly, Ghulam Mohammed Sadiq of the Indian National Congress became the first Chief Minister of the state.
