    D it burns with a crackling sound Correct Answer Incorrect Answer

    Solution

    Take a cotton wick dipped in a pure honey and light with a match stick. Pure honey will burn. If adulterated, the presence of water will not allow the honey to burn if it does; it will produce a cracking sound.
