Explanations:Understanding the geographical layout of South Asia is crucial for comprehending the geopolitical and economic relationships between the countries in the region. India, being a large country, shares its borders with several countries, each with its own unique geographical relationship.
India shares its eastern border with Myanmar, its northeastern border with Bhutan and Nepal, and its southeastern border with Bangladesh. However, Bangladesh is unique in that it borders India on three sides: the eastern, northeastern, and southeastern sides. This geographical feature makes Bangladesh the only country that borders India on three sides.
Myanmar, while sharing a border with India, does so only on the eastern side. Sri Lanka, being an island nation, does not share a land border with India at all, although it is connected by a maritime boundary. Nepal shares a border with India, but only on the northern side, not on three sides.
Understanding these geographical relationships is important for various reasons, including trade, security, and cultural exchanges. For example, the shared borders between India and Bangladesh facilitate significant trade and cultural interactions. The geographical position of Bangladesh relative to India also plays a role in regional politics and security concerns.
Therefore, the correct answer is Bangladesh, as it is the only country that borders India on three sides. This geographical fact is often tested in competitive examinations to assess the candidate's knowledge of Indian geography and its geopolitical context.
