Which row gives the correct arrangement and movement of the molecules in water and in ice when both are at a temperature of $0^{\circ}\text{C}$?
- Aa regular pattern of molecules in ice but not in water; molecules in both ice and water have the same average speed
- Ba regular pattern of molecules in ice but not in water; molecules in ice travel more slowly than those in water
- Ca regular pattern of molecules in both ice and water; molecules in ice travel more slowly than those in water
- Da regular pattern of molecules in both ice and water; molecules in both ice and water have the same average speed
