The correct option is D reversible changes
The changes that could be reversed are called reversible changes.
Wet clothes get dry by the process called evaporation i.e. water evaporates forming water vapours. Evaporation is an example of a reversible process. The water vapours formed condense to form clouds and they bring rains. Thus, water comes back to the surface of the Earth by precipitation.
Hence, drying of clothes is a reversible process.
