The correct option is (c).
Explanation
The Kaveri (Cauvery) is a major east-flowing river within the Peninsular Drainage System. It is distinct among peninsular rivers because it receives rainfall from both the South-West Monsoon (upper catchment) and the North-East Monsoon (lower catchment), making it nearly perennial.Statement 1 is Correct: The Kaveri rises at Talakaveri in the Brahmagiri range of the Western Ghats, located in the Kodagu district of Karnataka. It flows for approximately 800 km before reaching the sea.
Statement 2 is Incorrect: The river flows in a south-easterly direction through the states of Karnataka and Tamil Nadu. It drains into the Bay of Bengal at Poompuhar in the Nagapattinam district of Tamil Nadu. It does not flow westwards into the Arabian Sea.
Statement 3 is Correct: The Kaveri is joined by numerous tributaries throughout its course. Its significant tributaries include:
- Left Bank: Harangi, Hemavati, Shimsha, and Arkavathi.
- Right Bank: Lakshmantirtha, Kabini, Suvarnavathi, Bhavani, Noyyal, and Amravati.
Key Takeaway: The Kaveri originates in the Brahmagiri hills (Western Ghats), flows eastwards, and empties into the Bay of Bengal. Its major tributaries include the Hemavati, Kabini, Bhavani, and Amravati.
