Which of the following methods is suitable for preventing an iron frying pan from rusting?

Options

A. Applying grease
B. Applying paint
C. Applying a coating of zinc
D. All of the above

Answer

C

Explanation

The first two methods cannot be used to protect a frying pan because both grease and paints are organic matter which burn on heating. Therefore, a coating of zinc is usually applied. Zinc being more reactive than Fe does not allow rusting to occur.
