the answer is centipetal force
The centripetal force is the external force required to make a body follow a circular path at constant speed. The force is directed inward, toward the center of the circle. Hence it is a force requirement, not a particular kind of force. Any force (gravitational, electromagnetic, etc.) can act as a centripetal force. The term centripetal force comes from the Latin words centrum ("center") and petere ("tend towards", "strive for sth.").
The centripetal force always acts perpendicular to the direction of motion of the body. In the case of an object that moves along a circular arc with a changing speed, the net force on the body may be decomposed into a perpendicular component that changes the direction of motion (the centripetal force), and a parallel, or tangential component, that changes the speed.

Centripetal force, meaning a force directed toward a centre (= "inward").
The object itself appears to exert an outward force along the string (or whatever) that is holding it in circular motion, and that's centrifugal force. The two are therefore closely connected (equal and opposite, in fact).

Mr X is incorrect. The answer is "centripetal" force. "Centrifugal" force is actually an imaginary force (yes, it's true). To an observer on the earth, centrifugal force seems to exist because of the rotation of the earth, but in fact it is inertia and not a force in its own right.

The major hint is "uniform circular motion". That means the object moves at constant speed. Unlike what Count Uglino posted, that means there is NO tangential force. The only force is play is the one that forces the object to change direction. Think about spinning a child by the arms. In what direction is the force required to keep the child spinning? That is your answer.

Centripetal force. As opposed to centrifugal force which is the OUTWARD force operating on a rotating object.

centripetal force is the only inward force on your list, so even if I weren't sure, it would be right by default
