Model Answer

(a) i–3, ii–4, iii–2, iv–1

N.W. No.1 – Ganga (Prayagraj–Haldia); N.W. No.2 – Brahmaputra (Sadiya–Dhubri); N.W. No.3 – West-Coast Canal, Kerala; N.W. No.5 – Brahmani and Mahanadi delta channels.

Explanation

The textbook explicitly lists the five National Waterways with their corresponding rivers/regions. Students must memorise the NW numbers carefully — a common error is swapping NW1 and NW2 (Ganga vs Brahmaputra). Option (a) is the only one that correctly pairs all four.
