Explanations:The Bay of Bengal is a significant geographical feature that borders India on its eastern coast. It is a large body of water that is part of the Indian Ocean. The Bay of Bengal is bounded by India to the west, Bangladesh to the north, and Myanmar to the east. It is an important body of water for India due to its role in maritime trade, fishing, and other economic activities.
Geographically, the Bay of Bengal is a semi-enclosed sea, which means it is partially enclosed by land but still connected to the larger ocean. It is the largest bay in the world and is known for its significant depth and the presence of several major rivers that flow into it, such as the Ganges, Brahmaputra, and Meghna. These rivers contribute to the rich sediment and nutrient content of the bay, making it a fertile ground for marine life and a crucial fishing ground for the region.
Understanding the geographical layout of India's coastal borders is essential for comprehending the country's maritime geography and its strategic importance. The Arabian Sea, which borders India on the west, is a different body of water and is not relevant to the eastern coast. The Indian Ocean is a larger body of water that includes the Bay of Bengal, but it is not the specific body of water that borders India on the east. The Pacific Ocean is far to the east of India and does not border the country.
Thus, the Bay of Bengal is the correct answer as it is the large body of water that borders India on its east coast, playing a crucial role in the country's maritime and economic activities.
