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.
So if velocity is constant then yes tangential acceleration will be 0. Answer A is correct.

Don't be confused, he has stated that the velocity is same. Its always tangential. You can't say about direction Because you don't know where they are measuring the velocity of partial. Either it might be on same position or It might very.

When a particle is moving in circular path then its velocity will change its direction. As we know that velocity is a vector quantity. And change in velocity per unit time is acceleration. Thus this statement is incorrect.

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.

Basically, Tangential Acceleration is equal to (Radius*Angular Acceleration), as the velocity is uniform, there is no angular acceleration. Hence, only the centripetal acceleration exists.

Tangential acceleration is due to change in magnitude of velocity. So here the velocity is constant so the tangential acceleration will be zero. So the statement is correct.

Remember that tangential acceleration refers to the change in the magnitude of velocity, but not it's direction. Here metioned velocity is constant, so option A is correct.

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.

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.

Tangential velocity always changes its direction in a circular motion, and hence there exists a tangential acceleration. So the statement is incorrect.
