When the weight moves, it has kinetic energy. Is this energy the result of a transfer or a transformation of energy from the spring? A transfer of energy means that the energy does not change form but is shifted from one object to another.

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.

Then the answer would be d then

The magnets are probably damaged or there not strong enough to attached to the refrigerator
