As the girl in the picture begins to descend from the highest point of the swing, her potential energy is decreasing and her kinetic energy is increasing. This is because potential energy is highest at the top of the swing (the highest point) and as she comes down, it's converted into kinetic energy, which is highest at the lowest point of the swing.
Therefore, the correct statement is:
Kinetic energy is increasing, and potential energy is decreasing.
