The answer is D
Friction acts as a centripetal force in the case of a car turning. The friction creates a tangential force allowing the car to turn.
Tension can act as a centripetal force in the case of circles. Such as swinging a mass on a string, the tension force allows it to move in a curved path.
Gravity acts as a centripetal force in the case of satellites. The gravity keeps the satellite within the orbit.
