    water?
    A Its density exceeds that of water Correct Answer Incorrect Answer
    B Its density is lower than that of water Correct Answer Incorrect Answer
    C Its density equals that of water Correct Answer Incorrect Answer
    D None of the above explanations apply Correct Answer Incorrect Answer

    Solution

    Kerosene oil floats on water because it has a lower density compared to water. This physical property means that kerosene is lighter relative to an equal volume of water. The phenomenon demonstrates the principle of buoyancy, wherein objects or substances with lower density rise to the surface of denser liquids.
