Which one of the following water bodies separates the Andaman and the Nicobar islands?

  1. A.Gulf of Mannar
  2. B.Ten Degree Channel
  3. C.Eleven Degree Channel
  4. D.Palk Strait

Correct answer

B. Ten Degree Channel

Explanation

The correct answer is B, Ten Degree Channel. The Ten Degree Channel, which runs along roughly the 10° North parallel, separates the Andaman group from the Nicobar group.

The channel lies between Little Andaman in the north and Car Nicobar in the south and is about 150 km wide. It links the Bay of Bengal with the Andaman Sea. Further south, the Great Channel separates Great Nicobar from Sumatra in Indonesia. On the Lakshadweep side, the Nine Degree Channel separates Minicoy from the main group of islands and the Eight Degree Channel separates Minicoy from the Maldives.

A is wrong because the Gulf of Mannar lies between the south-east coast of Tamil Nadu and Sri Lanka. C is wrong because the Eleven Degree Channel is not the strait between the Andaman and Nicobar groups. D is wrong because the Palk Strait separates Tamil Nadu from the Jaffna region of Sri Lanka, north of Adam's Bridge.

Exam tip: Ten Degree between Andaman and Nicobar, Nine Degree and Eight Degree around Minicoy, Great Channel between Great Nicobar and Sumatra.
