Explanation:

- Article 370 was a provision in the Indian Constitution that granted special autonomy to the region of Jammu and Kashmir.

- This article allowed Jammu and Kashmir to have its own constitution and decision-making powers except in certain areas like defense, communications, and foreign affairs.

- It was revoked by the Indian government in August 2019 as part of efforts to fully integrate the region with India.

2. Sikkim: Not connected to Article 370. Sikkim joined India with a different arrangement.

3. Nagaland: Part of the northeastern states, has special provisions under a different article, not Article 370.

4. Kashmir: Correct. This region was directly affected by Article 370's provisions.
