Correct answer: (a) 1, 2 and 4
Explanation
- A
1, 2 and 4
(a) 1, 2 and 4. Bandarpunch feeds the Yamuna (Yamunotri group). Bara Shigri, Himachal’s largest glacier, belongs to the Chandra–Chenab system. Siachen’s melt feeds the Nubra, which joins the Shyok–Indus. Milam is a Goriganga glacier, not Mandakini (Kedarnath / Chorabari). Zemu feeds the Teesta, not the Manas. So 1, 2 and 4 is the official key.
- B
1, 3 and 4
(b) 1, 3 and 4. Pair 3 (Milam–Mandakini) is wrong, so this is not the key.
- C
2 and 5
(c) 2 and 5. Pair 5 (Zemu–Manas) is wrong, so this is not the key.
- D
3 and 5
(d) 3 and 5. Both remaining pairs are the mismatches, so this is not the key.
Summary. Official key is (a) 1, 2 and 4. Lock the rivers: Yamuna–Bandarpunch, Chenab–Bara Shigri, Nubra–Siachen. Mandakini is a Ganga headstream at Kedarnath; Milam is Kumaon’s Gori. Zemu is Sikkim’s Teesta source glacier; Manas is a Bhutan–Assam river. Honour the stored letter (a).
