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

The correct answer is 2 and 4 only.

To determine which rivers originate from the Eastern Ghats, let us analyze the origin of each river listed in the question:

1. Brahmani River: The Brahmani is a major inter-state river in eastern India. It is formed by the confluence of the Sankh and South Koel rivers near Rourkela in Odisha. The South Koel originates near Ranchi in the Chota Nagpur Plateau of Jharkhand. Therefore, the Brahmani River does not rise from the Eastern Ghats.

2. Nagavali River: The Nagavali River (also known as the Langulya) is an important east-flowing river in eastern India. It originates from a hill near Lakhbahal village in the Kalahandi district of Odisha, which forms a part of the Eastern Ghats. It flows through Odisha and Andhra Pradesh before emptying into the Bay of Bengal. Hence, it rises from the Eastern Ghats.

3. Subarnarekha River: The Subarnarekha River originates near Nagri village in the Ranchi district of the Chota Nagpur Plateau in Jharkhand. It flows through Jharkhand, West Bengal, and Odisha before discharging into the Bay of Bengal. Thus, it does not rise from the Eastern Ghats.

4. Vamsadhara River: The Vamsadhara River is an important east-flowing river between Rushikulya and Godavari. It originates from the Thuamul Rampur region in the Kalahandi district of Odisha, which lies in the Eastern Ghats region. It flows through Odisha and Andhra Pradesh before merging into the Bay of Bengal. Hence, it rises from the Eastern Ghats.

Based on the origins detailed above:

• Rivers originating from the Eastern Ghats: Nagavali (2) and Vamsadhara (4).

• Rivers originating from the Chota Nagpur Plateau: Brahmani (1) and Subarnarekha (3).

Thus, the correct combination of rivers that rise from the Eastern Ghats is 2 and 4 only.
