    A Iron Correct Answer Incorrect Answer
    B Aluminum Correct Answer Incorrect Answer
    C Copper Correct Answer Incorrect Answer
    D Zinc Correct Answer Incorrect Answer

    Solution

    A lightning rod is a metal rod or metallic object mounted on top of a building, electrically bonded using a wire or electrical conductor to interface with ground or "earth" through an electrode, engineered to protect the building in the event of lightning strike. If lightning targets the building it will preferentially strike the rod and be conducted to ground through the wire, instead of passing through the building, where it could start a fire or cause electrocution.
