Solution

The correct option is C Assertion is correct but Reason is incorrect
Circular motion is restricted and thus the centripetal force plays no part in actually changing the velocity of the motion. Projectile motion is unrestricted and hence

$\to v = \to u + \to a t$ still holds true. Reason is not correct as gravity does have a role in circular motion as well as projectile motion.
