Solution

The correct option is A Melting of ice
Temporary (or reversible) changes are the changes that can be reversed or undone.

During melting, ice absorbs heat and changes its state from solid to liquid. This change can be reversed by freezing of the water.
During burning of wood, rusting of iron and frying of egg, the original substance is destroyed, and a completely new substance is formed. These changes cannot be reversed, therefore they are not temporary.
