Assertion : A thin uniform rod is undergoing fixed axis rotation about one of its end with variable angular acceleration. Then acceleration vector of any two moving points on the rod can not be parallel at an instant of time. Reason : For a rod undergoing fixed axis rotation, the velocity of any two moving points on the rod at different distances from centre of rotation are different.

1. If both assertion and reason are true and reason is the correct explanation of assertion.
2. If both assertion and reason are true but reason is not the correct explanation of assertion.
3. If Assertion is true but reason is false.
4. If both assertion and reason are false.

Correct answer: If both assertion and reason are false.
