Explanation: Kerala is a state in the southwestern part of India, known for its lush green landscapes, backwaters, and rich cultural heritage. Geographically, Kerala is situated between 8°18' and 12°47' north latitude and 74°52' and 77°24' east longitude. The state is bordered by the Arabian Sea to the west, the Western Ghats to the east, and the states of Karnataka and Tamil Nadu to the north and south, respectively.
The Arabian Sea, a part of the Indian Ocean, is a significant body of water that forms the western boundary of Kerala. It is a marginal sea of the Indian Ocean, extending from the mouth of the Indus River (in Pakistan) to the Strait of Bab-el-Mandeb (between the Horn of Africa and the Arabian Peninsula). The Arabian Sea is crucial for Kerala's economy, as it supports fishing, shipping, and tourism industries.
The misconception that the Bay of Bengal could be the western boundary of Kerala arises from a misunderstanding of the geographical layout of the Indian subcontinent. The Bay of Bengal is located to the east of India and borders states like West Bengal, Odisha, and Andhra Pradesh. It is not connected to Kerala, which is situated on the western coast.
Similarly, the Indian Ocean, while a larger body of water that includes the Arabian Sea, is not the specific body of water that forms the western boundary of Kerala. The Pacific Ocean, located on the eastern side of the Indian subcontinent, is even farther away and does not border Kerala.
In summary, the Arabian Sea is the correct answer as it is the body of water that forms the western boundary of Kerala, supporting the state's coastal geography and economy. Understanding the geographical boundaries of Kerala is essential for comprehending its unique position within the Indian subcontinent and its relationship with the surrounding bodies of water.
