Correct Option (A):
The pairs 1, 2, and 4 are correctly matched.
- Pair 1: Bandarpunch - Yamuna. The Yamuna River originates from the Yamunotri glacier, which is located on the western flank of the Bandarpunch massif in Uttarakhand.
- Pair 2: Bara Shigri - Chenab. The Bara Shigri glacier, situated in the Chandra valley of Himachal Pradesh, feeds the Chandra River. The Chandra River subsequently merges with the Bhaga River to form the Chenab River.
- Pair 4: Siachen - Nubra. The Siachen glacier, located in the eastern Karakoram range of Ladakh, drains into the Nubra River. The Nubra River is a tributary of the Shyok River, which ultimately flows into the Indus River.
Incorrect Options:
- Pair 3: Milam - Mandakini. This pair is incorrectly matched. The Milam glacier in the Kumaon Himalayas (Uttarakhand) is the source of the Goriganga River. The Mandakini River originates from the Chorabari (Kedarnath) glacier and joins the Alaknanda River at Rudraprayag.
- Pair 5: Zemu - Manas. This pair is incorrectly matched. The Zemu glacier, located at the base of Kangchenjunga in Sikkim, contributes to the Teesta River system. The Manas River originates in Bhutan and flows into Assam, having no direct association with the Zemu glacier.
