Tamil Nadu shares the waters of the Kaveri River with the state of:

Karnataka
Kerala
Andhra Pradesh
Telangana

The correct answer is (a) Karnataka.

The Kaveri River is a major river in India, flowing through the states of Karnataka, Tamil Nadu, Kerala, and Puducherry. It is the lifeline of the Cauvery basin, which is home to over 60 million people. The river is a source of water for irrigation, drinking water, and hydroelectric power.

The Kaveri River originates in the Western Ghats in Karnataka. It flows through the state of Karnataka for about 300 kilometers before entering Tamil Nadu. The river then flows through Tamil Nadu for about 200 kilometers before entering Kerala. The river finally enters Puducherry and flows into the Bay of Bengal.

The Kaveri River is a major source of water for irrigation in the Cauvery basin. The river is also a source of drinking water for millions of people in the basin. The river is also a source of hydroelectric power.

The Kaveri River is a major source of conflict between the states of Karnataka and Tamil Nadu. The two states have been fighting over the sharing of the river’s water for many years. The conflict has led to violence and protests.

The Kaveri River is a beautiful and important river. It is a source of life for millions of people. The river is also a source of conflict. The conflict over the sharing of the river’s water is a major problem. The conflict needs to be resolved in a way that is fair to all the states that share the river.

The other options are incorrect because they are not states that share the waters of the Kaveri River.
