The correct option is (a).
Explanation
The Kaveri (Cauvery) is a major east-flowing river of the Peninsular drainage system. It rises in the Brahmagiri range of the Western Ghats in Karnataka and flows through Karnataka and Tamil Nadu before draining into the Bay of Bengal. Its basin covers a significant portion of Southern India.
Statement-wise Analysis:
- Statement 1 is Correct: The River Kaveri forms the Shivasamudram Falls, which is the second biggest waterfall in India. The hydroelectric power station established here in 1902 was one of the first in Asia. The electricity generated from this project is supplied to Mysuru, Bengaluru, and the Kolar Gold Fields.
- Statement 2 is Incorrect: The Kaveri basin extends over the states of Tamil Nadu, Karnataka, Kerala, and the Union Territory of Puducherry. It does not drain parts of Maharashtra, Gujarat, or Rajasthan. Rivers such as the Narmada, Tapi, Mahi, and Sabarmati drain the regions of Maharashtra, Gujarat, and Rajasthan.
Key Takeaway:
The Kaveri River basin is geographically limited to the southern states of Karnataka, Tamil Nadu, Kerala, and Puducherry, distinguishing it from other peninsular rivers like the Godavari or Krishna which have basins extending into Maharashtra.
