The correct statement is:
The toasting of the marshmallow is a chemical change.
Toasting a marshmallow involves the process of caramelization and potentially the production of new compounds as the sugars in the marshmallow break down and react under heat, which constitutes a chemical change.
The other options incorrectly categorize physical and chemical changes. For example, the melting of chocolate is a physical change, and digestion of food involves chemical changes. Additionally, burning wood is also a chemical change due to combustion.
