Solution
The correct option is D All of these
Rusting of iron can be prevented by the following methods :
(i) Iron is protected from rusting by coating it with a thin layer of another metal which is more reactive than iron. Zinc is commonly used for covering iron surfaces. The process of covering iron with zinc is called galvanization.
(ii) Iron articles are often painted to protect them from rusting.
(iii) Lubrication of iron articles prevents rusting. This is known as greasing.
