A non-electronic conductor is A. Iron B. Gas Carbon C. Copper Sulphate D. None of these

The correct answer is: D. None of these

A non-electronic conductor is a material that does not conduct electricity well. Examples of non-electronic conductors include:

• Insulators: These materials have a high resistance to the flow of electricity. Examples of insulators include rubber, plastic, and glass.
• Semiconductors: These materials have a resistance to the flow of electricity that is intermediate between that of insulators and conductors. Examples of semiconductors include silicon and germanium.
• Dielectrics: These materials are insulators that can be polarized by an electric field. Examples of dielectrics include water, paper, and ceramics.

Iron, gas carbon, and copper sulphate are all conductors of electricity. Iron is a metal that is a good conductor of electricity. Gas carbon is a form of carbon that is also a good conductor of electricity. Copper sulphate is a salt that is a good conductor of electricity.
