The National Waterway which stretches from Kottapuram to Kollam is:

Question

Accepted Answer

The National Waterway that stretches from Kottapuram to Kollam is indeed NW 3. Here's why:

*   **Why NW 3 is correct:** National Waterway 3 (NW 3), also known as the West Coast Canal, is a 205 km long waterway in Kerala, India. It extends from Kottapuram to Kollam, passing through important towns and cities along the Kerala coast. This aligns perfectly with the question's description.

*   **Why NW 4 is incorrect:** National Waterway 4 (NW 4) is located along the East Coast of India, connecting Kakinada to Puducherry. It does not run through Kerala or connect Kottapuram and Kollam.

*   **Why NW 2 is incorrect:** National Waterway 2 (NW 2) is the Brahmaputra River, stretching from Dhubri to Sadiya in Assam. It is located in Northeast India and has no connection to Kerala or the West Coast Canal.

*   **Why NW 5 is incorrect:** National Waterway 5 (NW 5) is the East Coast Canal integrated with Brahmani River and Mahanadi River Delta. It is located in Odisha and West Bengal, and therefore, not relevant to the Kottapuram-Kollam stretch in Kerala.

Therefore, based on the geographical locations and routes of the National Waterways, NW 3 is the only option that accurately describes the waterway connecting Kottapuram to Kollam.
