During which period were coal mines nationalised in India?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 1971-1975.
Coal mines in India were nationalised during 1971–1975. The process took place in two stages. In 1971–1972, the government nationalised coking coal mines, which are crucial for steel production. This move aimed to ensure a steady coal supply for industries, improve working conditions, and prevent exploitation by private owners. Later, in 1973, non-coking coal mines were also nationalised to further strengthen energy security and regulate production. Nationalisation helped the government control pricing, improve safety standards, and boost overall coal production, making the coal sector more efficient and aligned with India’s economic and industrial growth objectives.
