Explanation: The National Coal Development Corporation (NCDC) is a public sector enterprise under the Ministry of Coal in India. It was established in 1956, which is the correct answer to the question. The NCDC plays a crucial role in the exploration, development, and management of coal resources in the country. The establishment of the NCDC in 1956 was part of a broader strategy by the Indian government to promote the development of the coal industry, which was essential for the country's industrial growth and energy needs.
The year 1956 was a significant period in the history of the Indian coal industry. The Indian government, under the leadership of Prime Minister Jawaharlal Nehru, was focused on industrializing the country and ensuring a steady supply of coal for various industries. The NCDC was established to facilitate the exploration of new coalfields, the development of existing coal mines, and the overall management of coal resources to meet the growing demand for energy.
It is important to note that the NCDC was not the only organization established during this period to support the coal industry. The Coal Mines Nationalisation Act of 1973 further consolidated the government's control over the coal sector, which had a significant impact on the operations and responsibilities of the NCDC.
Understanding the establishment of the NCDC in 1956 is crucial for comprehending the broader context of India's industrial development and the role of public sector enterprises in the country's economic growth. The NCDC continues to play a vital role in the Indian coal industry, contributing to the nation's energy security and industrial development.
In summary, the correct answer is 1956, as this was the year when the National Coal Development Corporation was established to promote the development of the coal industry in India. This event is a significant milestone in the history of the Indian coal sector and the broader context of the country's industrialization efforts.
