    1. Best Answer

      [C] PVC
      Graphite cannot be used as insulating material. Polyvinyl Chloride (PVC) is used as an insulating material for covering electric wires. Sulphur is a non-metal although non-conductor of electricity. So, cannot be used as insulating material. Hence, you should go with option [C].
