Correct answer: (c) Both 1 and 2
Explanation
- A
Only 2
Only 2. The Himalayan hydro potential itself is also keyed.
- B
Neither 1 nor 2
Neither. Both NCERT limbs hold.
- C
Both 1 and 2
Both 1 and 2. Himalayan rivers have huge hydel potential. Eastern UP and Bihar cannot tap the stretch to their north because that Himalaya lies in Nepal.
- D
Only 1
Only 1. The Nepal-border limb is also keyed.
Summary. Official key is (c) both. Himalayan hydel is large; eastern UP–Bihar cannot use the Nepal Himalaya immediately north of them. Also note: Run-of-river — Uttarakhand–HP projects; not the Bihar plain; Kosi / Gandak — Rise in Nepal; floods Bihar more than they power it; Indus–Ganga–Brahmaputra — India’s three Himalayan hydel belts; Treaty hydel — India–Nepal (Pancheshwar etc.) is the workaround.
