Explanations:Kerala is a state located in the southwestern part of India, known for its lush green landscapes, backwaters, and beautiful beaches. Geographically, Kerala is bounded 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 is a crucial geographical feature that defines Kerala's western boundary. It is a part of the larger Indian Ocean and is bounded by India to the east, Pakistan and Iran to the north, and the Arabian Peninsula to the west. The Arabian Sea is a significant body of water for Kerala, as it influences the state's climate, economy, and culture. Kerala's coastline along the Arabian Sea is approximately 590 kilometers long, and it is dotted with numerous ports and fishing villages.
It is important to understand the geographical layout of the Indian subcontinent to correctly identify the bodies of water that border different states. The Bay of Bengal, for instance, is located on the eastern coast of India and borders states like West Bengal, Odisha, and Andhra Pradesh. The Indian Ocean is a larger body of water that includes the Arabian Sea, but it is not the specific body of water that forms Kerala's western boundary. The Pacific Ocean is located on the opposite side of the Indian Ocean and does not border Kerala.
Thus, the Arabian Sea is the correct answer as it is the specific body of water that forms the western boundary of Kerala. Understanding the geographical boundaries of states is essential for comprehending their physical and cultural characteristics, as well as their economic and environmental interactions.
