Answer
D - The spring has more elastic potential energy than the weight has kinetic energy.
In Diagram 3, when the spring is held stationary, the weight pulls the spring down, causing it to have elastic potential energy due to its deformation. Since the system is not in motion, the weight at that moment has kinetic energy equal to zero. Therefore, the elastic potential energy in the spring is greater than the kinetic energy of the weight.
