    The answer is A) sugar dissolving in warm water

    Explanation:

    That's the only example where the composition of the molecules does not change.

    The sugar scatters among the water molecules but they are still sugar molecules.

    In all the other cases there are chemical reactions that change the molecular structure of the materials you started with.
