Arrange the following passes from West to East direction : 1. Bara Lacha La 2. Shipki La 3. Jelep La 4. Bomdi La Select the correct answer using the code given below.

The mountain passes of the Himalayas are arranged from West to East based on their longitudinal positions across the states of Himachal Pradesh, Sikkim, and Arunachal Pradesh. Bara Lacha La is located in the Lahaul and Spiti district of Himachal Pradesh, connecting Manali to Leh [2]. Shipki La is situated further east within Himachal Pradesh in the Kinnaur district, where the Satluj River enters India [1]. Moving further east into the state of Sikkim, Jelep La connects the East Sikkim district with Tibet. Finally, Bomdi La is located in the easternmost state of Arunachal Pradesh, situated to the east of Bhutan [3]. Therefore, the correct West to East sequence is Bara Lacha La (Himachal Pradesh), Shipki La (Himachal Pradesh), Jelep La (Sikkim), and Bomdi La (Arunachal Pradesh), corresponding to the order 1-2-3-4.
