As the girl in the picture starts to come down from her highest point while swinging, her potential energy decreases because she is lowering her height relative to the ground, and her kinetic energy increases as she accelerates due to gravity. Therefore, the best statement that describes the changes in energy as she begins to descend is:
Kinetic energy is increasing, and potential energy is decreasing.
