Correct option is B
Correct Answer: (B) Brahmaputra river
Explanation:National Waterway 2 (NW-2) in India refers to the Brahmaputra river. It is one of the designated national waterways that spans from Sadiya in Assam to Dhubri in the same state, covering a distance of about 891 km. This waterway is crucial for inland water transport, particularly for the transport of goods and cargo.
Other Option:
- West Coast canal and Champakara and Udyogmandal canals: This refers to National Waterway 3, not NW-2.
- Kakinada canal (Kakinada to Rajahmundry): This is part of National Waterway 4, not NW-2.
- East Coast canal and Matai river: This is also part of National Waterway 5, not NW-2.
Thus, National Waterway 2 is the Brahmaputra river.
