Explanation
The Ten Degree Channel separates the Andaman Islands (specifically Little Andaman) from the Nicobar Islands (specifically Car Nicobar) at the 10°N latitude in the Bay of Bengal. It is approximately 150 km wide and serves as a significant maritime boundary between these two island groups.
Context for other options: - Nicobar and Sumatra: These are separated by the Great Channel (also known as the Six Degree Channel). - Maldives and Lakshadweep: The Eight Degree Channel separates the Maldives from Minicoy Island (the southernmost part of Lakshadweep), while the Nine Degree Channel separates Minicoy from the rest of the Lakshadweep archipelago. - Sumatra and Java: These Indonesian islands are separated by the Sunda Strait, which connects the Java Sea to the Indian Ocean.
