Solution
The correct option is C P.E is gained
Because the molecules are held together by strong bonds in a solid, you need to input energy (do work) to break the bonds and increase the separation of the molecules.
Potential energy is the name you give to the energy that the molecules get when you do this work on them. (PE gained= work done)
