    in water?
    A Iron is denser than Mercury Correct Answer Incorrect Answer
    B Iron is less dense than Mercury Correct Answer Incorrect Answer
    C Iron and Mercury have the same density Correct Answer Incorrect Answer
    D None of the above Correct Answer Incorrect Answer

    Solution

    Iron sinks in water due to its higher density compared to water but floats in mercury because mercury's density is greater than that of iron. This property of relative density determines whether substances float or sink in different mediums.
