Explanation: The Kaveri River, also known as Cauvery, is a major river in South India that flows through the states of Karnataka and Tamil Nadu. It is one of the most important rivers in the region, playing a crucial role in the agricultural and economic activities of these states. The river originates in the Western Ghats, specifically in the Brahmagiri hills of the Kodagu district in Karnataka. It then flows eastward, passing through the states of Karnataka and Tamil Nadu, before finally emptying into the Bay of Bengal.
The Kaveri River is approximately 760 kilometers long and is a perennial river, meaning it flows throughout the year. It is fed by both rainwater and the melting snow from the Western Ghats. The river basin covers a significant area, including parts of Karnataka, Tamil Nadu, Kerala, and Puducherry. The river is divided into two main segments: the upper Kaveri, which flows through Karnataka, and the lower Kaveri, which flows through Tamil Nadu.
The Kaveri River is not only a source of water for irrigation but also supports a rich biodiversity. It is home to various species of fish and other aquatic life. The river also has significant cultural and religious importance, with several temples and pilgrimage sites located along its banks. The river is a subject of the Kaveri Water Disputes Tribunal, which has been involved in resolving water-sharing disputes between Karnataka and Tamil Nadu.
In contrast, the other rivers mentioned in the options do not flow through Karnataka and Tamil Nadu. The Sindh (Indus) River flows through Pakistan, the Brahmaputra River flows through the northeastern states of India, and the Ganga River flows through the northern states of India. Therefore, the Kaveri River is the correct answer as it is the major river that flows through Karnataka and Tamil Nadu.
