The correct option is A
True

A chemical change is a change in which the chemical composition of the substance changes because of the formation of a new substance.

Rusting of iron is a chemical change because a reddish-brown layer (rust) forms over the surface of iron when iron reacts with oxygen and moisture present in the atmosphere. In this process, the chemical composition of iron changes and a new substance, i.e., rust is formed.
