- Burning of Paper: This is a chemical change. Burning transforms paper into ash and gases, and cannot be reversed.
- Cooking of an Egg: Cooking causes permanent denaturation of proteins, making it irreversible.
- Freezing of Water: This is a physical change. Water can be frozen and then melted back to liquid, making it reversible.
- Rusting of Iron: This is a chemical change. Iron reacts with oxygen to form rust, which cannot be easily reversed.
Thus, option C, freezing of water, is the reversible change.
