Solution
The correct options are
B Painting
C Galvanization
Rusting of iron occurs when it comes in contact with air and water. Thus, to prevent rusting, the surface of iron objects is coated so that it does come in contact with air or water.
Rusting of iron can be prevented by the following methods : (i) By coating the objects with a thin layer of another metal which is more reactive than iron. Zinc is commonly used for coating iron surfaces. The process of coating iron with zinc is called galvanization.
(ii) Painting- Applying a layer of paint over the surface of objects.
