The correct answer is option 2 - Lakshadweep from Maldives.

The Eight Degree Channel is a body of water that separates two island groups - Lakshadweep and Maldives. Lakshadweep is a group of islands located off the southwest coast of India, while the Maldives is an independent island nation located to the southwest of Sri Lanka. The Eight Degree Channel runs between these two island groups and serves as a maritime boundary between them.

Option 1 - India from Sri Lanka - is incorrect because the Eight Degree Channel does not separate these two countries. The Palk Strait, located further north, separates India from Sri Lanka.

Option 3 - Andaman from Nicobar Islands - is incorrect because the Andaman and Nicobar Islands are part of the same archipelago and are not separated by the Eight Degree Channel.

Option 4 - Indira Point from Indonesia - is incorrect because Indira Point is located in the Andaman and Nicobar Islands and is not separated by the Eight Degree Channel from Indonesia.

Therefore, the correct answer is option 2 - the Eight Degree Channel separates Lakshadweep from Maldives.
