Answer
Applying a coating of zinc
Reason — Applying grease is not suitable as it will contaminate the food cooked in the frying pan making it inedible. Applying paint is not suitable as heating and washing the pan several times will cause the paint to peel off very soon. Hence, galvanisation i.e., applying a coating of zinc is the most suitable method to prevent an iron frying pan from rusting.
