The answer for this question is part B that is Water molecules move from their fixed position.
This is because when water is freeze it is in a solid condition that means the molecules are held together tightly and are are vibrating in their fixed positions.
As soon as the molecules gain energy they start to move around from their fixed positions and turn into a liquid.
In the process of doing so ice melts and becomes water.
