Question

Galvanizing works because __________.

• A. Metal becomes inert.
• B. Coating becomes inert.
• C. The coating acts as a sacrifice coating, protecting the metal inside.
• D. Galvanizing prevents rusting.

The correct option is C

The coating acts as a sacrifice coating, protecting the metal inside.

Zinc is coated on iron during galvanization. Zinc being more reactive delays the rusting of iron by sacrificing itself for oxidation attack.
