Understanding Himalayan Pass Arrangement: East to West

The question asks for the correct arrangement of specific Himalayan passes when ordered from east to west. To answer this, we need to know the approximate geographical location of each pass.

Locations of the Himalayan Passes

Let's identify the states or regions where these passes are located:

• Jelep La: Located in Sikkim, connecting Sikkim with Lhasa, Tibet. Sikkim is in the eastern part of the Indian Himalayas.
• Niti Pass: Located in Uttarakhand, connecting Uttarakhand with Tibet. Uttarakhand is west of Sikkim.
• Shipkila Pass: Located in Himachal Pradesh, connecting Himachal Pradesh with Tibet. Himachal Pradesh is west of Uttarakhand.
• Zojila Pass: Located in Jammu & Kashmir/Ladakh, connecting Srinagar with Kargil and Leh. This region is in the westernmost part of the Indian Himalayas related to the given passes.

Determining the East to West Order

Based on their locations from east to west along the Himalayan range within India, the order is:

1. Sikkim (Jelep La)
2. Uttarakhand (Niti Pass)
3. Himachal Pradesh (Shipkila Pass)
4. Jammu & Kashmir/Ladakh (Zojila Pass)

Therefore, the correct order of the passes from east to west is Jelep La - Niti - Shipkila - Zojila.

Analyzing the Options

Let's compare our determined order with the given options:

• Option 1: Jelep La - Niti - Shipkila - Zojila
• Option 2: Zojila - Shipkila - Niti - Jelep La (This is West to East)
• Option 3: Jelep La - Shipkila - Zojila - Niti (Incorrect sequence)
• Option 4: Niti - Zojila - Jelep La - Shipkila (Incorrect sequence)

Only Option 1 matches the correct east to west arrangement of the Himalayan passes.
