Correct Option (D):
The Godavari River is the largest river of Peninsular India, often referred to as the Dakshin Ganga. It originates at Trimbakeshwar in Maharashtra and flows eastward into the Bay of Bengal. Among the given rivers, Indravati and Pranahita are significant tributaries of the Godavari.
- Indravati: This is a major left bank tributary of the Godavari. It originates in the Kalahandi district of Odisha and flows through the Bastar region of Chhattisgarh before joining the Godavari.
- Pranahita: This is another important left bank tributary, formed by the confluence of the Wardha and Wainganga rivers in Maharashtra. It is notable for its large catchment area.
Incorrect Options:
- Vamsadhara: This is an independent east-flowing river. It originates in the Kalahandi and Rayagada districts of Odisha and flows through Odisha and Andhra Pradesh, directly emptying into the Bay of Bengal at Kalingapatnam. It is not a tributary of the Godavari.
- Pennar: This is also an independent east-flowing river. It originates in the Nandi Hills of Karnataka and flows through Andhra Pradesh, draining directly into the Bay of Bengal. It is not part of the Godavari river system.
Therefore, only Indravati (2) and Pranahita (3) are tributaries of the Godavari.
