The correct answer is option 3: 6. Zonal Councils are autonomous bodies created under the States Reorganization Act of 1956 in India. They are established to promote cooperative federalism and ensure the balanced development of the country. There are 6 Zonal Councils in India, each covering multiple states and Union Territories. These Zonal Councils are named after their respective zones: Northern, Western, Eastern, Southern, Central, and North Eastern. Each Zonal Council consists of the Chief Ministers of the member states and Union Territories, as well as certain Union Ministers. They meet periodically to discuss and coordinate matters of common interest, such as infrastructure, economic planning, and social development, among others.
