The correct answer is: d) Bhakra Nangal Dam.
The Bhakra Nangal Dam is a gravity dam on the Sutlej River in the Bilaspur district of Himachal Pradesh, India. It is one of the largest dams in India and the world, and is a major source of hydroelectric power and irrigation water for the states of Punjab, Haryana, Rajasthan, and Delhi.
The dam was built between 1954 and 1963, and was inaugurated by Prime Minister Jawaharlal Nehru on 15 November 1963. It is named after the villages of Bhakra and Nangal, which were submerged by the reservoir.
The dam is 225 meters (738 feet) high and 518 meters (1,700 feet) long. It has a gross storage capacity of 9.33 cubic kilometers (32.6 billion cubic feet) and a live storage capacity of 5.92 cubic kilometers (20.3 billion cubic feet).
The dam generates 1,320 megawatts of hydroelectric power. It is also a major source of irrigation water for the Bhakra Canal and the Nangal Canal.
The dam has had a significant impact on the environment and the people who live in the area. The reservoir has submerged several villages and towns, and has displaced thousands of people. The dam has also changed the flow of the Sutlej River, which has had an impact on the ecology of the river.
Despite the environmental and social impacts, the Bhakra Nangal Dam is a major engineering feat and has played a significant role in the development of India.
