With reference to India, consider the following : 1. The Inter-State Council 2. The National Security Council 3. Zonal Councils How many of the above were established as per the provisions of the Constitution of India?

Only the Inter-State Council is a constitutional body, established under Article 263 of the Constitution of India. Zonal Councils are often mistaken for constitutional bodies but are actually statutory bodies created by the States Reorganisation Act of 1956, while the National Security Council is an executive body established by a government order in 1998. This question tests the ability to distinguish between constitutional, statutory, and executive bodies within the Indian administrative framework.
