Answer: option C.

In fact that is the definition of centripetal force.

A force acting over an object in motion will make that the object change its velocity. If the force is perpendicular to the velocity, then the object will change the direction of the velocity. If the force is constant then the change in velocity is continuos and uniform which will make a uniform circular movement.
