Explanation:
The Cauvery River is a major river in southern India, flowing through the states of Karnataka and Tamil Nadu. It is known for its importance in agriculture and irrigation in the region. The river is fed by several tributaries, which are smaller rivers that flow into the main river.
Tributaries of the Cauvery River:
Among the given options, three of them are tributaries of the Cauvery River. They are:
1. Malaprabha: The Malaprabha River is a tributary of the Krishna River in the state of Karnataka. It originates in the Western Ghats and joins the Cauvery River near the town of Almatti. It is an important water source for irrigation in the region.
2. Harangi: The Harangi River is a tributary of the Cauvery River in the state of Karnataka. It originates in the Western Ghats and flows through the districts of Kodagu and Hassan before joining the Cauvery River near the town of Kushalnagar. The Harangi Dam is built on this river, which helps in regulating the flow of water into the Cauvery River.
3. Arkavati: The Arkavati River is a tributary of the Cauvery River in the state of Karnataka. It originates in the Nandi Hills and flows through the districts of Ramanagara and Bangalore Rural before joining the Cauvery River near the town of Sangama. The river is known for its scenic beauty and is an important source of water for the city of Bangalore.
Therefore, the correct answer is option 'b' - Only three of the given rivers (Malaprabha, Harangi, and Arkavati) are tributaries of the Cauvery River. The other two rivers, Bhavani and Doni, are not tributaries of the Cauvery River.
