a. Rhea is standing still after kicking the ball, and Sean is running.

Tony Duncan · Answer 2

Since the ball is moving at the same speed in Rhea's reference frame relative the speed it was kicked at, Rhea must be standing still. Since the ball is moving faster than the speed at which it was kicked from Sean's reference frame, he must be running towards the ball.

This means A is the correct answer here!
