RAS question

National Waterway 1 (Ganga) runs from:

Correct answer: (B) Allahabad to Haldia (1,620 km).

National Waterway 1 runs on the Ganga-Bhagirathi-Hooghly river system from Allahabad, now Prayagraj, to Haldia over 1,620 km.

  1. (A)

    Delhi to Kolkata

  2. (B)

    Allahabad to Haldia (1,620 km)

  3. (C)

    Varanasi to Kolkata

  4. (D)

    Patna to Haldia

Explanation

National Waterway 1 is the Allahabad-to-Haldia stretch of the Ganga-Bhagirathi-Hooghly river system. That makes option B correct: the route is not merely a lower-Ganga link near Kolkata, but a 1,620 km national waterway beginning at Allahabad, now Prayagraj, and ending at Haldia. The point tested is the full terminal-to-terminal extent, because several plausible options name important cities on or near the system but cut off one end of the official waterway. NW-1 is also linked with the Jal Marg Vikas Project, under which this waterway is being developed with World Bank aid.

Why the other options are wrong

  • (A) Delhi to Kolkata is wrong because the Ganga route of NW-1 does not run through Delhi, so Delhi cannot be its starting point.
  • (C) Varanasi to Kolkata is too narrow because NW-1 begins upstream at Allahabad, now Prayagraj, rather than at Varanasi.
  • (D) Patna to Haldia captures only a downstream segment and misses the official starting point at Allahabad, now Prayagraj.

Concept

This tests inland waterways under Indian transport geography, especially the national-waterway network and major river corridors. It recurs in RAS because NW-1 combines a named river system, terminal cities, length, and an infrastructure project in one factual map-based question.
