Answer:

d

Step-by-step explanation:

the molecules in steam rising from boiling water are moving the fastest because heat energy is actively breaking the bonds binding the water molecules together and simultaneously moving the water from one state to another (liquid to gas). At this extreme temperature, the molecules are very frantic compared to the others which are not being stimulated by heat.

The molecules of water in ice, for example, are static and tightly packed.
