    Water is the best insulator.

    Explanation:

    Specific Heat Capacity is the amount of heat required to raise the temperature of 1 kg of a substance by 1 K.

    A good insulator has a high specific heat capacity.

    This means that it absorbs more heat for raising its temperature by 1 K.

    This is a property of a good insulator.

    Among the given materials, water has the highest specific heat capacity.

    Hence, water is the best insulator.
