Consider the following rivers :

1. Brahmani
2. Nagavali
3. Subarnarekha
4. Vamsadhara Which of the above rise from the Eastern Ghats?

Nagavali River originates from the eastern slopes of the Eastern Ghats, near Lakhbahal in the Kalahandi district of Odisha, at an altitude of 1,300 meters.

Vamsadhara River rises in the Eastern Ghats on the border of the Kalahandi district and Rayagada district of Odisha. It travels approximately 254 kilometers before joining the Bay of Bengal at Kalingapatnam, Andhra Pradesh.

Brahmani River is formed by the confluence of the Sankh and South Koel rivers near Rourkela. The Sankh originates near the Jharkhand-Chhattisgarh border, and the South Koel originates near Lohardaga, Jharkhand, both of which are part of the Chota Nagpur Plateau.

Subarnarekha River originates near Ranchi and flows through Jharkhand, West Bengal, and Odisha before meeting the Bay of Bengal.

Statement 2 is correct: Nagavali originates from the Eastern Ghats. Statement 4 is correct: Vamsadhara originates from the Eastern Ghats. Statement 1 is incorrect: Brahmani does not originate from the Eastern Ghats. Statement 3 is incorrect: Subarnarekha does not originate from the Eastern Ghats.

Hence, option b is the correct answer.
