Which of the following Articles is related to Jammu & Kashmir state of India?

Article 370

The correct answer is Option 3 - Article 370

Article 370 of the Indian Constitution grants special autonomous status to the state of Jammu and Kashmir. It was incorporated into the Constitution in 1949 to provide temporary provisions with respect to the state's governance and autonomy.
Article 370 was intended as a temporary provision, allowing the state of Jammu and Kashmir to have its own Constitution and decision-making powers, except in certain matters such as defense, foreign affairs, finance, and communications, which remained under the jurisdiction of the central government.
Article 370 granted significant autonomy to the state of Jammu and Kashmir, allowing it to have its own Constitution, flag, and special rights for its residents, including rights related to property ownership and employment.
On August 5, 2019, the Government of India revoked the special status granted to Jammu and Kashmir under Article 370 and bifurcated the state into two Union Territories: Jammu and Kashmir, and Ladakh. This move was accompanied by significant constitutional changes, altering the governance structure of the region.
