Hey there!
The more energy a substance is, the more movement it has.
The energy of a substance determines its state of matter.
From least to most energy, it goes solid, liquid, gas.
So it needs to be going from a lower energy state to a higher energy state.
The only one that goes from a lower energy state to a higher energy state is C. H2O (l) --> H2O (g).
Hope this helps!
