A particle cannot move in a circular path with uniform velocity as the direction of the particle is changing continuously. Hence the statement is incorrect.

Because the velocity is Constant.

This is hypothetical question as velocity can never be constant in a circular path. We all know that speed can remain constant but in a circular path at every instant the direction is changing, as a result the velocity has to change (velocity =speed+direction).
So if velocity is constant then yes tangential acceleration will be 0. Answer A is correct.

Here body moves with centrifugal acceleration.

Constant v, it means v = rw, it means w is also constant, so no angular acceleration, so no tangential acceleration.

Non-uniform circular motion is any case in which an object moving in a circular path has a varying speed. The tangential acceleration is non-zero; the speed is changing.

In a circular motion the velocity is constant so there will be no tangential acceleration. But since the direction of the particle keeps on changing, there will be radial acceleration towards its center.

Acceleration means change in velocity with time. Here velocity is constant. So it has no acceleration.

A body is said to be moving with the uniform velocity when it has no acceleration.

@Bhoopendra singh.
In circular motion the direction is always tangential.
