Assertion : Neutrons penetrate mater more readily as compared to protons.

Reason : Neutrons are slightly more massive than protons.

A

If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

B

If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

C
