Assertion-Reason on Uniform Circular Motion

Assertion: In uniform circular motion tangential acceleration of particle is zero.
Reason: In uniform circular motion net force on particle is always directed towards centre of circular path.
 
Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Both Assertion and Reason are true but Reason is not correct explanation of Assertion.
Assertion is true but Reason is false.
Assertion and Reason are false.

Solution:

Tangential acceleration is zero because speed is constant. The net force is centripetal, which is directed towards the center. Thus, both are true but the Reason is not the explanation of the Assertion.
