The correct option is 2 only
Explanation
The Krishna River is the second-largest east-flowing river in the Peninsular India drainage system. It originates in the Western Ghats and flows across the Deccan Plateau before draining into the Bay of Bengal.
Statement-wise Analysis:
- Statement 1 is Incorrect: The Krishna River rises from a spring near Mahabaleshwar in the Sahyadri range (Western Ghats) in the state of Maharashtra at an elevation of about 1,337 meters.
- Statement 2 is Correct: The Koyna, Bhima, and Tungabhadra are all major tributaries of the Krishna River. The Tungabhadra is formed by the confluence of the Tunga and Bhadra rivers and joins the Krishna River near Kurnool in Andhra Pradesh. It is not a tributary of the Godavari.
- Statement 3 is Incorrect: The Krishna River basin extends over Maharashtra, Karnataka, and Andhra Pradesh (including Telangana). The largest share of the catchment area lies in Karnataka (approximately 44%), followed by Andhra Pradesh (approximately 29%) and Maharashtra (approximately 27%).
Key Takeaway:
The Tungabhadra is the most important tributary of the Krishna River, not the Godavari. The largest portion of the Krishna basin lies within the state of Karnataka.
