The correct sequence of following passes in Himalaya from West towards East is :
(a) Banihal (b) Baralacha (c) Bomdila (d) Jelep La

Question

Accepted Answer

The correct sequence of the passes in the Himalayas from West to East is given as Option 4: a, b, d, c. Let's provide a detailed explanation to justify why this is the correct sequence and why the other options are incorrect.

### Explanation for Option 4: a, b, d, c

1. **Banihal Pass (a):** 
   - Located in the Pir Panjal range of the Himalayas, Banihal Pass is situated in the Indian state of Jammu and Kashmir. It serves as a crucial link between the Kashmir Valley and the outer Himalayas. Being the westernmost pass in the given options, it logically comes first in the sequence.

2. **Baralacha Pass (b):**
   - Baralacha Pass is located in the Zanskar range of the Himalayas in Himachal Pradesh. It connects the Lahaul district in Himachal Pradesh to the Ladakh region. Positioned east of Banihal Pass, it is the next in the sequence.

3. **Jelep La (d):**
   - Jelep La is a high mountain pass in the eastern Himalayas, located in the Indian state of Sikkim. It connects India with Tibet and is situated further east compared to Baralacha Pass.

4. **Bomdila Pass (c):**
   - Bomdila Pass is located in the northeastern part of India, in the state of Arunachal Pradesh. It is the easternmost pass among the given options, making it the last in the sequence.

### Why Other Options are Incorrect:

- **Option 1: a, c, b, d**
  - This sequence incorrectly places Bomdila Pass (c) before Baralacha Pass (b) and Jelep La (d). Bomdila is located further east than both Baralacha and Jelep La, making this sequence incorrect.

- **Option 2: d, a, b, c**
  - This sequence starts with Jelep La (d), which is incorrect as Jelep La is located further east than Banihal (a) and Baralacha (b). Therefore, it cannot be the first in the sequence.

- **Option 3: b, a, c, d**
  - This sequence incorrectly places Baralacha Pass (b) before Banihal Pass (a). Since Banihal is located to the west of Baralacha, this order is incorrect.

By following the geographical locations of these passes from west to east, Option 4 correctly sequences them as Banihal, Baralacha, Jelep La, and Bomdila. This logical ordering based on their longitudinal positions supports Option 4 as the correct answer.
