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

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

C. If assertion is true but reason is false

Step-by-step solution

The assertion is true because heavy - water is a better moderator than ordinary water. This is because heavy water absorbs fewer neutrons than normal water.
