Explanations:India shares international borders with seven countries, and the length of these borders varies significantly. Understanding the relative lengths of these borders is essential for geographical knowledge and for competitive examinations that test such information. The correct order of the countries by the length of their borders with India, from longest to shortest, is as follows:
1. Bangladesh: India shares the longest international border with Bangladesh, which is approximately 4,096.7 kilometers (2,545.7 miles). This border is significant due to the geographical proximity and the shared history between the two countries.
2. China: The border with China is the second longest, spanning about 3,380 kilometers (2,100 miles). This border is complex due to the disputed areas and the mountainous terrain of the Himalayas.
3. Pakistan: The border with Pakistan is the third longest, measuring around 3,323 kilometers (2,065 miles). This border is significant due to the historical and political tensions between the two countries.
4. Nepal: The border with Nepal is the fourth longest, stretching approximately 1,751 kilometers (1,088 miles). This border is notable for the mountainous region and the cultural ties between the two countries.

It is important to note that the exact lengths of these borders can vary slightly depending on the source and the method of measurement. However, the relative order of the countries by the length of their borders with India remains consistent. Understanding these lengths and the order of the countries is crucial for geographical knowledge and for answering questions related to India's international borders in competitive examinations.
