Explanations:The question tests the knowledge of major dam projects and their associated rivers in India, with a specific focus on Andhra Pradesh. The correct answer is Option A: Nagarjuna Sagar: River Krishna.
Nagarjuna Sagar is a significant dam and hydroelectric project located on the River Krishna in Andhra Pradesh. It is one of the largest and most important dam projects in India. The dam was constructed between 1955 and 1967 and is known for its role in irrigation and power generation. The reservoir created by the dam is one of the largest man-made lakes in the world, covering an area of about 190 square kilometers.
The River Krishna is one of the major rivers in southern India, originating in the Western Ghats in Maharashtra and flowing through Karnataka and Andhra Pradesh before emptying into the Bay of Bengal. The river is a vital source of water for irrigation, drinking, and industrial purposes in these states.
It is important to note that the other options listed in the question are incorrect. The Kararpara project is not associated with the River Kosi, which is located in the northeastern part of India. The Matatila project is not related to the Chambal River, which is located in central India. The Tawa project is not associated with the River Satlej, which is located in the northern part of India.
Understanding the geographical location and river systems of Andhra Pradesh is crucial for correctly identifying the dam projects and their associated rivers. This knowledge is particularly important for competitive examinations such as the UPSC, SSC, Bank PO, and State PSC, where questions on Indian geography and infrastructure are common.
