Solution

The correct option is B

galvanization


One of the simple ways to prevent rusting is to apply a coating of paint or grease on the surface of iron. In fact, these coats should be applied regularly to prevent rusting. Another way to prevent rusting is to deposit a layer of a metal like chromium or zinc on iron.This process of depositing a layer of zinc on iron is known as galvanization.
