The correct option is B Third Five Year Plan
The third five year plan (1961-1966) emphasized on the need to accelerate growth in agriculture and improve production. The country was hit by the Sino-Indian war during this war in 1962 and then a war with Pakistan in 1965. In 1965, a severe drought also hit the country and the agricultural economy of the country laid in shambles. The green revolution in India was then introduced, with modernized equipment, better seeds and fertilizers to increase yields.
