Which of the following describes the motion of water molecules in ice ?

The answer is option D "they are vibrating slightly." In ice the molecules are stuck together and shaking like a bunch of little people together trying to keep warm. Also its not option C because they do move all four stages move.

Its also not option A because as discussed solids move slower than a liquid.

Hope this helps!
