The Rohtang Pass, beneath which the Atal Tunnel has been built, lies in which state?

Show answer
Explanation
The correct answer is B, Himachal Pradesh. The Rohtang Pass lies on the Pir Panjal range in Himachal Pradesh and connects the Kullu valley with the Lahaul and Spiti district. Because the pass is closed by snow for several months each year, the Atal Tunnel, about nine kilometres long, was built beneath it and opened in October 2020 to keep Lahaul connected through the winter on the Manali to Leh route. Option A is wrong because the important passes of Uttarakhand are Mana, Niti and Lipulekh, all routes towards Tibet. Option C is wrong because Sikkim has Nathu La and Jelep La, which cross into the Chumbi valley. Option D is wrong because Arunachal Pradesh has Se La, Bomdi La, Diphu and Pangsau passes. A useful memory hook is that Rohtang and Banihal both cross the Pir Panjal and both now have tunnels under them.
