Choose the correct answer:

Assertion (A): Atolls are more common in the Atlantic ocean.

Reason(R): The marine population at the depth is less.

Atolls are not common in the Atlantic Ocean, rather it has the least number of Atolls. Atolls are more common in the Pacific and Indian Ocean. Hence, A is wrong.

The marine population increases with depth, and is not less. With depth comes little human intervention and stable ecosystem. Hence, R is also wrong.

Unfortunately, we do not have an option to allot to this kind of statements.

A is correct because atoll is a ring shaped coral reef which is abundantly found in the Atlantic ocean named as the Great Barrier reef. R is false because marine population is more at depth
