Banihal Pass is correctly matched with Jammu & Kashmir. This pass connects the Kashmir Valley with Jammu. The Banihal Tunnel (Jawahar Tunnel) beneath it provides all-weather access and is a vital link between the two regions.
Debsa Pass is located in Himachal Pradesh. This pass is a relatively lesser-known high-altitude pass in the Lahaul and Spiti district and is primarily used by trekkers and locals.
Niti Pass is located in Uttarakhand. It is a mountain pass in the Himalayas, close to the India-China border, and serves as a historical trade route between India and Tibet.
Chang La, however, is incorrectly matched with Sikkim. It is actually located in the Union Territory of Ladakh, not in Sikkim. The Chang La pass is one of the highest motorable passes in the world and is en route to Pangong Lake. Sikkim has passes like Nathu La and Jelep La.
