    A Aluminum Correct Answer Incorrect Answer
    B Lead Correct Answer Incorrect Answer
    C Silver Correct Answer Incorrect Answer
    D Zinc Correct Answer Incorrect Answer

    Solution

    Galvanization involves coating iron or steel with zinc to prevent rusting. The process involves dipping the base metal into molten zinc, forming a protective barrier that not only shields the iron from moisture and oxygen but also provides sacrificial protection—the zinc corrodes first, thereby offering extended protection to the underlying metal.
