Explanations:The question asks about the geographical location of an island in the Arabian Sea. To understand this, it is essential to know the geographical layout of India and its surrounding waters. The Arabian Sea is a part of the Indian Ocean that lies to the west of India and Pakistan, and it is bounded by the Arabian Peninsula to the west and the Indian subcontinent to the east.
Lakshadweep is an archipelago of islands located in the Arabian Sea, off the southwestern coast of India. It is one of the smallest Union Territories of India and is known for its beautiful beaches and coral reefs. The islands are part of the Arabian Sea and are situated to the west of the Indian mainland. The name "Lakshadweep" means "a hundred thousand islands" in Sanskrit, although the actual number of islands is much smaller.
On the other hand, the Andaman and Nicobar Islands are located in the Bay of Bengal, which is another part of the Indian Ocean that lies to the east of India. The Bay of Bengal is bounded by the Indian subcontinent to the west and the Andaman and Nicobar Islands to the east. Therefore, the Andaman and Nicobar Islands are not located in the Arabian Sea.
Rajasthan is a state in northwestern India and is not an island. It is a large state that is known for its deserts, palaces, and historical sites. It is located on the mainland and does not have any islands in the Arabian Sea.
Thus, the correct answer is Lakshadweep, as it is the only island group located in the Arabian Sea among the given options. This question tests the geographical knowledge of the student and their ability to distinguish between different island groups and their locations in relation to the Indian subcontinent.
