💡 Analysis & Explanation
Analyzing Northern Rivers ▼
The Brahmani and Subarnarekha rivers both have their origins in the Chota Nagpur Plateau region of Jharkhand. They flow south-eastwards to the Bay of Bengal but do not rise from the Eastern Ghats mountain range. Therefore, points 1 and 3 are incorrect.
Analyzing Southern Rivers ▼
The Nagavali river originates in the hills of the Eastern Ghats in the Kalahandi district of Odisha. Similarly, the Vamsadhara river rises in the Eastern Ghats bordering the Kalahandi and Rayagada districts of Odisha. Hence, points 2 and 4 are correct.
Conclusion ▼
Only Nagavali and Vamsadhara trace their source to the Eastern Ghats.
