Which row correctly shows how closely the molecules are packed and how they move in water and in ice when both are at a temperature of $0\degree\text{C}$?
- Amolecules in ice are further apart than molecules in water; molecules in both ice and water have the same average speed
- Bmolecules in ice are further apart than molecules in water; molecules in ice travel more slowly than those in water
- Cmolecules in ice are closer than molecules in water; molecules in ice travel more slowly than those in water
- Dmolecules in ice are closer than molecules in water; molecules in both ice and water have the same average speed
