Solution

The correct option is C The acceleration vector is tangent to the circle
A particle moving in a circle with a constant angular speed has centripetal acceleration only and zero tangential acceleration.
As $v = r w$
$w =$ constant $⟹ v =$ constant , thus $a_{v} = 0$
Also centripetal acceleration, $a_{c} = r w^{2}$ towards centre.
