Solution
The correct option is D Both (a) and (b) Iron reacts with oxygen and moisture to form iron oxide or rust. During this reaction, a layer of a rust is formed on the iron. Therefore it is a chemical change. No matter what we do, the rust damages the iron object to such an extent that we cannot get the iron object in its original shape and size.
