Explanation: Sri Lanka is an island nation located in the Indian Ocean, off the southern coast of India. It is separated from the Indian mainland by the Palk Strait and the Gulf of Mannar. The Palk Strait is a narrow body of water that connects the Bay of Bengal to the Arabian Sea, and it separates the island of Sri Lanka from the Indian state of Tamil Nadu. The Gulf of Mannar is a shallow body of water that lies between the southeastern coast of India and the northwestern coast of Sri Lanka.
Tamil Nadu is the southernmost state of India and has a long coastline along the Bay of Bengal and the Arabian Sea. The southernmost tip of Tamil Nadu is Kanyakumari, which is very close to Sri Lanka. The distance between the two is minimal, with the shortest distance being approximately 33 kilometers (21 miles) at the Palk Strait. This geographical proximity makes Tamil Nadu the closest Indian state to Sri Lanka.
The other options provided are incorrect for the following reasons:
- Goa is located on the western coast of India, far from the southern coast where Sri Lanka is located. It is part of the Konkan coast and does not share a direct maritime boundary with Sri Lanka.
- Kerala, while a southern state of India, is not the closest state to Sri Lanka. It is located to the west of Tamil Nadu and does not have a direct maritime boundary with Sri Lanka.
- Lakshadweep is a group of islands in the Arabian Sea, located off the coast of Kerala and Karnataka. It is not near the southern coast of India where Sri Lanka is located.
Understanding the geographical layout of the Indian subcontinent and the location of Sri Lanka relative to the Indian states is crucial for comprehending the proximity of these regions. This knowledge is essential for various competitive examinations and general geographical awareness.
