A) Krishna
B) Pinakini
C) Hemavathi
D) Sharavati

Answer 1

Hint:
The river Cauvery flows through the states of Tamil Nadu and Karnataka. It is the third-largest river in South India, after Godavari and Krishna, and two tributaries are joined near Krishnaraja Sagar.

Complete answer:
Cauvery River rises at Talakaveri in the Brahmagiri range which is located in the Western Ghats. The length of this river is 805 km (500 mi). The catchment area of this river is 81,155 sq. km (31,334 sq. mi). The tributaries that join Cauvery from left are Harangi, Shimsha, Hemavati and Arkavathy. Lakshmana Tirtha, Bhavani, Amaravati, Kabini, Noyyal and Moyar are the tributaries that join from the right. The basin of this river covers three states, which are Tamil Nadu, Karnataka, Kerala, and one Union Territory, which is Puducherry. This river flows south-east and finally merges in the Bay of Bengal. It forms an island in the Chamarajanagar district which is called Shivanasamudra. On either side of this island, there is a scenic Shivanasamudra Falls that descend about 100 m (330 ft). This river is a source for an extensive irrigation system and for hydroelectric power. This river forms two islands as it leaves the Kodagu hill and flows onto the Deccan plateau. The Cauvery is a basis for the Ranganathittu Bird Sanctuary which is 3 km away from Srirangapatna. There are two tributaries that join the River Cauvery near Krishnaraja Sagar, which are Hemavathi and Lakshmana Tirtha.

Thus, option (C) is correct.

Note:
The River Cauvery is sacred to the people of South India and is worshipped as the Goddess Kaveriamma.
