Solution

The correct option is C It is directed towards the centre of the circle.
An object in a uniform circular motion moves in a circular path with a constant speed. Since the direction of the object changes continuously, the acceleration acts towards the centre of the circle.
As the velocity is along the tangent, the acceleration is perpendicular to the velocity.
