Assertion : Heavy water is a better moderator than normal water.
Reason : Heavy water absorbs neutrons more efficiently than normal water.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reasonb is false

D

If both assertion and reason are false.
