The correct answer is option 2, Article 370.

Article 370 is a provision in the Constitution of India that provides special autonomous status to the state of Jammu and Kashmir. This article grants several special powers and exemptions to the state, including the ability to have its own constitution, flag, and separate laws.

Option 1, Article 238, is incorrect as it does not apply to Jammu and Kashmir. Article 238 deals with the Union Territories under the jurisdiction of the Indian government.

Option 3, Article 371, is also incorrect. Article 371 contains special provisions for states like Maharashtra, Gujarat, and Nagaland, but not for Jammu and Kashmir.

Option 4, Article 371G, is also incorrect. Article 371G pertains to the special provisions for the state of Mizoram, not Jammu and Kashmir.

Therefore, the correct answer to the question is Article 370 as it is the constitutional provision that applies to the state of Jammu and Kashmir, providing it with special autonomous status.
