Arunachal Pradesh shares its international boundary with which of the following combinations of countries?

Introduction / Context:
North eastern India is bordered by several neighbouring countries, and Arunachal Pradesh is a key frontier state in this region. Understanding which countries share borders with each Indian state is a vital part of political geography. This question asks specifically about the combination of countries that share an international boundary with Arunachal Pradesh.

Given Data / Assumptions:
• The state under consideration is Arunachal Pradesh. • Options list combinations of Bhutan, Bangladesh, China and Myanmar. • We assume current internationally recognised borders as taught in Indian geography texts. • The task is to select the set that matches the actual border situation.

Concept / Approach:
Arunachal Pradesh lies on the north eastern frontier of India. To its north and north east it borders the Tibet region which is under Chinese control, to its west it has a border with Bhutan, and to its east and south east it shares a boundary with Myanmar. Bangladesh lies to the south and south west of Assam and does not directly touch Arunachal Pradesh. Therefore, the correct combination is Bhutan, China and Myanmar.

Step-by-Step Solution:
Step 1: Visualise the position of Arunachal Pradesh on the map, north of Assam and close to the eastern Himalayas. Step 2: Recall that to the west of Arunachal Pradesh lies Bhutan, sharing a relatively short border. Step 3: Remember that the long northern boundary of Arunachal Pradesh runs along the Himalayan crest with the Tibet Autonomous Region, administratively under China. Step 4: To the east and south east, Arunachal Pradesh borders Myanmar. Step 5: Bangladesh lies well to the south of Assam and Meghalaya and has no direct boundary with Arunachal Pradesh, so any combination involving Bangladesh can be rejected.

Verification / Alternative check:
Maps of India that show international borders clearly mark the boundary of Arunachal Pradesh with China to the north, with Myanmar on the east and south east, and with Bhutan on the west. Question banks and textbooks describing north eastern border states explicitly mention China, Bhutan and Myanmar as the three neighbours of Arunachal Pradesh.

Why Other Options Are Wrong:
Option A: Includes Bangladesh instead of Myanmar, but Bangladesh does not share any direct border with Arunachal Pradesh. Option B: Also includes Bangladesh and omits Bhutan, which is incorrect as Arunachal Pradesh clearly borders Bhutan to the west. Option D: Replaces China with Bangladesh, which is geographically inaccurate since the main long northern border of Arunachal Pradesh is with the Tibet region administered by China.

Common Pitfalls:
Students sometimes remember that Bangladesh is near the north eastern region and assume it borders every north eastern state, which is not true. Another mistake is to forget about the short western boundary with Bhutan, focusing only on China and Myanmar. Regular practice with outline maps can help solidify these border relationships.

Final Answer:
Arunachal Pradesh shares its international boundary with Bhutan, China and Myanmar.
