The correct answer is: C. September, 1961

The 1st Amendment Act of Jammu and Kashmir Constitution came into force on 10 September 1961. It was enacted by the Jammu and Kashmir Legislative Assembly on 25 August 1961 and assented to by the President of India on 2 September 1961.

The main purpose of the amendment was to provide for the appointment of a Chief Justice of the Jammu and Kashmir High Court. The amendment also made certain other changes to the Constitution, such as increasing the number of seats in the Legislative Assembly and providing for the appointment of a Public Service Commission.

The amendment was passed in response to the growing demand for greater autonomy for the state of Jammu and Kashmir. The amendment was seen as a way of giving the state more control over its own affairs.

The amendment was met with some opposition from certain sections of the population, who felt that it gave too much power to the state government. However, the amendment was ultimately passed and has been in force since 1961.
