Correct option is B
The correct answer is (b) Gasherbrum.
Gasherbrum is the pass of the Siachen Glacier that is not in India.
India has administered the entire Siachen Glacier, including its major passes, as part of the union territory of Ladakh since 1984. However, Pakistan controls the region west of the Saltoro Ridge, including the Baltoro Glacier, Baltoro Muztagh, and K2.
The Siachen Glacier is the largest glacier in the Himalayas-Karakoram region and the second longest glacier outside of the polar regions.
Additional Information:
- Gyong La: Located in the Siachen region, but primarily situated near the boundary between India and Pakistan.
- Gasherbrum: Part of the Karakoram range, lies near the Pakistan-China border, not fully within India.
- Saltoro: Located entirely in India, near the Siachen Glacier.
- Vilafondala: Does not exist as a recognized pass or location related to the Siachen region.
