The correct answer is (b), Prime Minister.
The National Development Council (NDC) is a high-level planning body in India. It was set up in 1952 by the Planning Commission to advise the government on planning matters. The NDC is chaired by the Prime Minister and its members include the Union Ministers, Chief Ministers of States, and representatives of the Planning Commission, the Reserve Bank of India, and other important national institutions.
The NDC meets at least once a year to review the progress of the Five Year Plans and to discuss the economic situation of the country. It also makes recommendations to the government on matters relating to planning and development.
The NDC is an important body in the Indian planning process. It provides a forum for the government and the states to discuss and coordinate their planning efforts. It also helps to ensure that the plans are implemented effectively.
The other options are incorrect. The President is the head of state of India and does not have a role in the planning process. The Finance Minister is responsible for the country’s finances, but does not have a direct role in the planning process. None of the above is the correct answer because the Prime Minister is the Chairman of the National Development Council.
