i'd say c, but i'm not really sure about a steel is also a conductor. compared to other metals such as alluminium or copper it is a bad conductor, but compared to wood or air, it is a good conductor. anyway, if it asks for multiple answers, i guess you should try to go with a and c plastic and glass are insulators.
