Nepal shares international borders with several Indian states, but it does not share any border with which of the following states?

Introduction / Context:
Border based questions are very common in Indian geography. Nepal is a Himalayan country that lies to the north of India and shares long land boundaries with certain Indian states. This question flips the usual pattern by asking which given state does not touch Nepal at all, even though it may be geographically close to the region. Distinguishing between neighbouring and non neighbouring states helps you build a precise mental map of the northern frontier.

Given Data / Assumptions:

- The neighbour in focus is Nepal.

- Options include Uttarakhand, Haryana, West Bengal, Sikkim and Bihar, all located in northern or eastern India.

- It is assumed that you can recall the list of states that share borders with Nepal: Uttarakhand, Uttar Pradesh, Bihar, West Bengal and Sikkim.

- Based on that list, you must identify the state that is not part of this group.

Concept / Approach:
The India Nepal border extends from Uttarakhand in the west to Sikkim and West Bengal in the east. The states that share a direct boundary with Nepal are Uttarakhand, Uttar Pradesh, Bihar, West Bengal and Sikkim. Haryana lies to the southwest of Uttarakhand and shares borders with states like Punjab, Himachal Pradesh, Uttar Pradesh and Rajasthan, but its boundary does not reach up to Nepal. Therefore, the correct approach is to list the actual border states and then pick the option that is missing from that list, which is Haryana.

Step-by-Step Solution:
Step 1: Write down or recall from memory the Indian states that share a border with Nepal: Uttarakhand, Uttar Pradesh, Bihar, West Bengal and Sikkim. Step 2: Compare this list with the options given in the question. Step 3: Notice that Uttarakhand appears both in the list and among the options, so it does share a border with Nepal. Step 4: West Bengal and Sikkim also appear in both lists and are known to touch Nepal's boundary on the eastern side. Step 5: Bihar shares a long stretch of border with Nepal in the central part of the frontier. Step 6: Haryana is present in the options but does not appear in the correct list of border states, which means it does not share a boundary with Nepal. Step 7: Conclude that Haryana is the correct answer.

Verification / Alternative Check:
Look at a mental or physical map of northern India. You will see a horizontal strip of states touching Nepal. From west to east they are Uttarakhand, Uttar Pradesh, Bihar, West Bengal and Sikkim. Haryana lies further south and west and is separated from Nepal by the state of Uttarakhand and parts of Uttar Pradesh. There is no direct contact line between Haryana and Nepal on the map, which confirms that Haryana does not share an international border with Nepal.

Why Other Options Are Wrong:
Uttarakhand shares a significant border with Nepal in the western Himalayan region. West Bengal touches Nepal on its northern side near the Darjeeling region. Sikkim lies to the east of Nepal and shares a shorter but important frontier with it. Bihar shares a long border with Nepal in the central Indo Gangetic region, making it an important border state.

Common Pitfalls:
Because Haryana is very close to the Himalayan region and directly touches Uttarakhand and Uttar Pradesh, some students incorrectly assume that it must also touch Nepal. A similar confusion can arise with states near Bhutan or China. The best way to avoid this is to thoroughly practise blank maps, tracing the exact boundaries of India's neighbours. Doing this a few times makes it easier to answer any questions about which states share or do not share international borders.

Final Answer:
Nepal does not share its border with the Indian state of Haryana.
