Solution

The correct option is D Water wash
Rusting of iron takes place when the metal is exposed continuously to atmospheric oxygen and moisture.

Galvanization, painting and greasing prevent rusting by cutting off the contact of the metal with oxygen and moisture. Whereas water wash has no role in preventing the rusting of iron as it comes in direct contact with water.
