The correct answer is:
**D. The particles in the liquid are moving faster than they were in the solid.**
When a substance undergoes a phase change from solid to liquid (melting), the particles gain energy and begin to move more freely, resulting in faster movement compared to when they were in the solid state, where they are more closely packed and vibrate in fixed positions.
