$Assertion$ : If collision occurs between two elastic bodies their kinetic energy decreases during the time of collision.
$Reason$ : During collision intermolecular space decreases and hence elastic potential energy increases

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

If the Assertion is correct but Reason is incorrect.

D

If both the Assertion and Reason are incorrect.
