B Correct answer
Explanation

Rusting is the specific term for the corrosion of iron, where iron reacts with oxygen and moisture to form iron oxide (Fe₂O₃·nH₂O). This is a type of oxidation reaction that weakens the metal over time. Roasting is a metallurgical process, while rating is not related to corrosion.
