Match List – I with List – II and choose the correct answer using the code…

Match-the-following questions on Himalayan passes test direct locational recall: each pass named in List – I lies in exactly one Indian state, usually identifiable by the broad Himalayan stretch it sits in (the western Himalaya covers Himachal Pradesh and Uttarakhand, while the eastern Himalaya covers Sikkim and Arunachal Pradesh). Solving the match means knowing each pass's state individually, since a wrong pairing usually comes from confusing two passes that lie in the same broad region.

• Lipulekh Pass lies in Uttarakhand's Pithoragarh district, on the route used for the Kailash-Mansarovar Yatra pilgrimage — pairing A-1.

• Nathu La lies in Sikkim, on the historic trade route linking Sikkim to Tibet across the eastern Himalaya — pairing B-2.

• Bomdila lies in Arunachal Pradesh's West Kameng district, on the road connecting Tawang to the rest of the state — pairing C-3.

• Debsa Pass lies in Himachal Pradesh, connecting the Kullu and Spiti valleys in the western Himalaya — pairing D-4.

Every incorrect option in this question arises from interchanging two passes that share a Himalayan region — either the two western passes (Lipulekh and Debsa, split between Uttarakhand and Himachal Pradesh) or the two eastern passes (Nathu La and Bomdila, split between Sikkim and Arunachal Pradesh). Checking each pass against its own state individually, rather than assuming a symmetric pattern, confirms A-1, B-2, C-3, D-4 as the only combination where every pass sits in its correct state.
