✓ Answer: B Zinc
Galvanization is a method of protecting iron from rusting by coating it with a thin layer of zinc. This zinc layer acts as a protective barrier, preventing moisture and oxygen from reaching the iron surface. Additionally, even if the coating is damaged, zinc will preferentially corrode instead of the iron, offering sacrificial protection.
