"for example a solid piece of ice melting into liquid, at the moment of melting the average kinetic energy of the molecules does not change. the heat used to break the bonds between the ice molecules as they turn into liquid phase"

I think that its D.
(let me know if im wrong please)
I hope this helps ^-^
