(b) Applying paint
(c) Applying a coating of zinc
(d) All of the above.

Answer 1

(c) Applying a coating of zinc
(We can also apply grease and paint to prevent iron from rusting. However, in case of iron frying pan, grease and paint cannot be applied because when the pan will be heated and washed again and again, the coating of grease and paint would get destroyed.)
