Explanation: Mumbai, the capital city of Maharashtra, is a significant urban center located on the western coast of India. It is situated on the banks of the Arabian Sea, which is a part of the Indian Ocean. The Arabian Sea is a crucial body of water that borders the western coast of India and is an important route for maritime trade and transportation.
Mumbai's location on the Arabian Sea has played a pivotal role in its development as a major commercial and financial hub. The city's port, one of the oldest and busiest in India, has been a key factor in its economic growth. The port facilitates the import and export of goods, contributing significantly to the city's and the country's economy.
Understanding the geographical context of Mumbai is essential for comprehending its historical, economic, and cultural significance. The city's coastal location has influenced its architecture, lifestyle, and economic activities. For instance, the city's skyline is dominated by high-rise buildings, many of which are located close to the sea, reflecting the importance of the waterfront in urban planning and development.
In contrast, the other options provided do not fit the criteria of being situated on the bank of the sea. Jodhpur, located in Rajasthan, is an inland city known for its historical forts and palaces. Gandhi Nagar, the capital of Gujarat, is also an inland city and does not have a coastline. Nainital, a hill station in Uttarakhand, is known for its lakes and scenic beauty but is not located on the sea.
Thus, the correct answer is Mumbai, as it is the only city among the options that is situated on the bank of the Arabian Sea, making it a significant coastal city in Maharashtra and India.
