Explanation: To understand the geographical layout of India's coastlines, it is essential to recognize the different bodies of water that surround the country. India is a peninsula, meaning it is surrounded by water on three sides. The Arabian Sea borders India on the west, the Bay of Bengal on the east, and the Indian Ocean to the south.
The Bay of Bengal is a significant part of the Indian Ocean and is the largest bay in the world. It is bounded by India and Bangladesh to the west and north, and by Myanmar and Thailand to the east. The Bay of Bengal is crucial for India's maritime trade, as it provides access to the ports of Kolkata, Chennai, and Visakhapatnam, among others. It also plays a vital role in the monsoon weather patterns that affect the eastern part of India, bringing much-needed rainfall to the region.
The Arabian Sea, on the other hand, borders India on the west and is part of the Indian Ocean. It is bounded by India to the east, Pakistan to the north, and the Arabian Peninsula to the west. The Arabian Sea is important for India's western ports, such as Mumbai and Kochi, and is a significant route for international trade.
The Indian Ocean is a vast body of water that encompasses both the Arabian Sea and the Bay of Bengal, among other smaller bodies of water. It is the third-largest ocean in the world and is bounded by Asia to the north, Africa to the west, and Australia to the east.
The Pacific Ocean, while a significant body of water, does not border India directly. It is located to the east of the Indian Ocean and is separated from India by the Asian continent.
In summary, the Bay of Bengal is the correct answer as it is the large body of water that borders India on its eastern coast. Understanding the geographical layout of India's coastlines and the bodies of water that surround it is crucial for comprehending the country's maritime trade, weather patterns, and overall geographical significance.
