Answer 1

Hint: The main river of the Tamil Nadu state is Kaveri. It originates in the Kodagu district of Karnataka. Kaveri river in its lower course drains the districts of Nagapattinam, Thanjavur, Thiruvarur and Tiruchirapalli of the Tamilnadu. Also, the Kollidam and the Vellar are flowing in the Tamil Nadu state.

Complete answer:
Kaveri is the Indian River flowing through two states of Karnataka and the Tamil Nadu. It rises at the Talakaveri in the Brahmagiri range of the Indian Western Ghats. It is in the Kodagu district of the state of Karnataka.

Vellar is the river and it originates in the Shevaroy Hills. It is running through the districts of Salem, Perambalur and Cuddalore. It is in the northern part of the Tamil Nadu state. Then after it drains into the Bay of Bengal near Parangipettai.

The Kollidam is the river of the southeastern part of India. The Kollidam river is the northern distributary segment of the Kaveri river. It further splits from the main branch of the Kaveri River at the island of Srirangam. Then it flows eastward into the Bay of Bengal. The distribution system of the Kollidam river lies at the lower anicut, which is its island.
The Kaveri, the Kollidam and the Vellar jointly drain through the central part of the Tamil Nadu state.

Hence, the correct answer is option B.

Note:
Kaveri, Kollidam and Vellar rivers are flowing in the central part of the TamilNadu state. These are the lifeline of the state and fulfilling its majority of the water needs.
