National Waterway 5 River Identification

National Waterway 5 (NW-5) is a designated waterway in India. It primarily covers parts of the Damodar Valley waterways and the East Coast Canal, linking the Mahanadi and Brahmani river systems.

Analyzing River Options for NW-5:

• Godavari River: This is a major river in peninsular India but is not part of NW-5.
• Damodar River: While the Damodar Valley Canal is part of NW-5's route, the river itself is primarily designated as National Waterway 2.
• Krishna River: Another major South Indian river, not associated with NW-5.
• Brahmani River: This river, along with the Mahanadi river delta, forms the core riverine stretch of National Waterway 5.

Therefore, the Brahmani river is the correct option as it is a key component of the National Waterway 5 route.
