The correct answer is (c), the Fourth Five Year Plan.
The Second Five Year Plan (1956-1961) focused on agriculture and heavy industry. The Third Five Year Plan (1961-1966) focused on agriculture, basic industries, and social services. The Fourth Five Year Plan (1969-1974) focused on self-reliance and zero net foreign aid. The Fifth Five Year Plan (1974-1979) focused on agricultural development, energy, and social justice.
The Fourth Five Year Plan was the first plan to declare its objective of self-reliance and zero net foreign aid. This was a major shift in India’s economic policy, which had previously relied heavily on foreign aid. The plan aimed to reduce India’s dependence on foreign imports and increase its exports. It also aimed to increase domestic production of essential goods and services.
The Fourth Five Year Plan was not entirely successful in achieving its objectives. India’s dependence on foreign aid did not decrease significantly, and its exports did not increase as much as planned. However, the plan did help to lay the foundation for India’s economic growth in the 1980s and 1990s.
