Best answer
Correct option is (c) Electrolytic solutions

For explanation: Electrolytic solutions are those that are capable of conducting an electrical current. They are generally ions, in which both positive and negative charges can move. Polymers and thermosets do not conduct electric charge. Electrons are the charge carriers in metallic conductors.
