    Answer : Option D

    Explanation :

    Either the wording of the question is wrong or it doesn’t have a correct option. A non-conductor is a substance which does not allow the passage of electricity. As a general rule, all metals (Iron, Mercury, etc) are good conductors. Nonmetals are non-conductors, except for carbon in the form of graphite and the gas carbon. Copper Sulphate is a good electrolyte (a liquid which allows the passage of electricity). So all the options given in the question are good electrical conductors.
