Solution

The correct option is A
True

Corrosion is a natural process, which takes place when a metal is attacked by a substance around it such as moisture. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment.
The products of corrosion of metals are often sulphides or oxides. Since a new product is formed and the change is irreversible, it can be categorised as a chemical change.
