The correct answer is: B) Tamil Nadu
The Kaveri River is a perennial river in India, flowing through the states of Karnataka, Tamil Nadu, Kerala, and Puducherry. It is the third-longest river in the Indian peninsula, after the Godavari and the Krishna rivers. The Kaveri basin is home to over 60 million people, and the river is a major source of water for irrigation, drinking water, and hydroelectric power.
Water disputes over the sharing of the Kaveri River have been a source of conflict between Karnataka and Tamil Nadu for many years. The two states have different views on how the water should be shared, and there have been several court cases and protests over the issue. In 2018, the Supreme Court of India ruled that Karnataka should release 192 tmcft of water to Tamil Nadu every year. However, Karnataka has refused to comply with the order, and the dispute remains unresolved.
The other options are incorrect because they are not states that share the Kaveri River. Kerala is located to the west of the Kaveri River, Andhra Pradesh is located to the east, and Maharashtra is located to the north.
