The answer is B. This is an example of a physical change. In my rough diagram, I show that Ice molecules are packed together. Water molecules are more spread move more freely, and gas molecules are even more spread apart and have the most freedom of motion. These molecules have not changed in chemical form, because they are all still H2O molecules, in different physical states.
