Which of the following best describes the public sector's role in the Indian economy during 1947–1991?

Correct Option: Dominant in core and heavy industries

Explanation:

During the period from 1947 to 1991, India adopted a mixed economy model with a strong emphasis on the public sector (the state). Following independence, the Indian economy faced severe challenges, including a lack of private capital, inadequate infrastructure, and underdeveloped basic industries.

To establish a strong industrial base, the government gave the public sector a leading and dominant role, particularly in core and heavy industries such as steel, heavy machinery, power generation, mining, and telecommunications. This policy was formalized through the Industrial Policy Resolutions of 1948 and 1956, and formed the backbone of the Five-Year Plans (especially the Second Five-Year Plan based on the Mahalanobis model).

Let us analyze the given options:

1. Dominant in core and heavy industries: Correct. The state strategically controlled and invested in basic, heavy, and strategic industries where private investment was either insufficient or not feasible due to high capital requirements and long gestation periods.

2. Only limited to agriculture: Incorrect. Agriculture was largely in the private domain of individual farmers, though the government supported it through infrastructure (like dams and irrigation) and policy reforms.

3. Minimal presence: Incorrect. The public sector had a pervasive and dominant presence across key economic sectors during this period, often referred to as the "License Raj" phase.

4. Focussed only on foreign trade: Incorrect. While state agencies like the State Trading Corporation (STC) managed aspects of foreign trade, the primary focus of the public sector was domestic heavy industrialization and import substitution.

Hence, the public sector was dominant in core and heavy industries during 1947–1991.
