Light is either potential energy or kinetic.
In short: Electromagnetic radiation is energy that is propagated in the form of electromagnetic waves
Best example of electromagnetic radiation is sunlight. Vsible light of sunlight is only a small portion of the EM spectrum. EM radiation is a form of energy that takes many forms, f.e.: microwaves, radiowaves, etc.
Fluid mechanics deals with pressure and internal forces in the fluid. So the correct answer should be a) how fluids do work.
If you put two solids in contact, there will be a contact force created between them. Since Pressure = Force / Area, the correct answer should be b) exert pressure on each other.
Energy is NEVER destroyed making this an interesting topic. In reality this energy is just isolated from that system and just changes states. You could do anything for your story, just make sure to include those points.
Hope this helped :)
