The correct answer is c. There is no component of force acting along the direction of motion of the satellite.

Explanation:

When a moving object is traveling in a circular orbit at a constant speed we assume it has a changing velocity, this is mainly because velocity is a vector quantity that rely on the speed the object is moving and direction, because of the variation of acceleration throughout the whole orbit and the lack of other force acting along the direction of motion of the satellite allows the object to travel at a constant speed, but variable acceleration.
