Explanations:Mumbai, one of the largest and most populous cities in India, is located on the western coast of the country. The Arabian Sea is a significant geographical feature that borders this coast. Understanding the geographical layout of India's coastline is crucial for comprehending the city's maritime connections and its strategic importance.
The Arabian Sea is a part of the Indian Ocean, but it is a distinct body of water that is bounded by the Arabian Peninsula to the west, the Indian subcontinent to the east, and the Horn of Africa to the south. It is an important water body for trade and commerce, connecting India to the Middle East and Africa.
On the other hand, the Bay of Bengal is located on the eastern coast of India, bordering states like West Bengal, Odisha, and Andhra Pradesh. It is a significant body of water for the eastern part of India, but it does not border Mumbai.
The Indian Ocean is a much larger body of water that encompasses both the Arabian Sea and the Bay of Bengal, but it is not the specific body of water that borders Mumbai's western coast. Therefore, the Arabian Sea is the correct answer to the question.
It is important to note that geographical knowledge is essential for understanding the location and significance of various cities and regions. Mumbai's location on the Arabian Sea makes it a crucial port city and a hub for maritime trade and commerce in India.
