The correct option is 2 only.
Explanation
During British colonial rule in India, the state's participation in the industrial sector was minimal. The colonial government did not actively promote a diversified industrial base, and the public sector's footprint was restricted to specific strategic areas required for administration and trade facilitation.
Statement-wise Analysis:
- Statement 1 is Incorrect: The public sector did not have a wide area of operation. It largely neglected the development of heavy industries and capital goods sectors, which are crucial for a self-reliant economy.
- Statement 2 is Correct: The operations of the public sector were strictly confined to critical infrastructure sectors. These included railways, power generation, communications, ports, and a few other departmental undertakings.
- Statement 3 is Incorrect: Due to the limited scope of operation and the overall underdevelopment of the industrial sector, the public sector's contribution to the Gross Domestic Product (GDP) was insignificant.
Key Takeaway:
The public sector under British rule was characterized by a limited scope, confined primarily to Railways, Power, Communications, and Ports, without a significant role in the country's GDP or heavy industrialization.
