Matter can exist in solid, liquid, and gas phases. The particles in each phase have different characteristic motions. Which row in the table correctly describes the motion of the particles in each phase?
| Solid | Liquid | Gas | |
|---|---|---|---|
| A | Vibrate about fixed positions | Slide past each other | Move rapidly in all directions |
| B | Vibrate about fixed positions | Move rapidly in all directions | Slide past each other |
| C | Move rapidly in all directions | Slide past each other | Vibrate about fixed positions |
| D | Slide past each other | Vibrate about fixed positions | Move rapidly in all directions |
