The correct answer is (a) Industrialization.
The First Five Year Plan was a plan for economic development in India. It was implemented from 1951 to 1956. The main objective of the plan was to increase the country’s industrial production. The plan was successful in achieving this objective, and India’s industrial production increased by 25% during the plan period.
The plan also focused on the development of agriculture, education, and health. However, the focus of the plan was on industrialization. This was because the Indian government believed that industrialization was the key to economic development.
The First Five Year Plan was a major turning point in India’s economic history. It laid the foundation for the country’s rapid economic growth in the decades that followed.
The other options are incorrect because they were not the priorities of the First Five Year Plan.
(b) Urbanization is the process of people moving from rural areas to urban areas. The First Five Year Plan did not focus on urbanization.
(c) Development of Agriculture is the process of improving the production of food and other agricultural products. The First Five Year Plan did focus on the development of agriculture, but it was not the top priority.
(d) Spread of Education is the process of making education available to more people. The First Five Year Plan did focus on the spread of education, but it was not the top priority.
