Which of these groups lists three good electrical conductors?

An electrical conductor is a material that allows electric charge to flow freely. Metals are generally excellent conductors due to their atomic structure, which features loosely bound electrons that can move easily from atom to atom. Gold, silver, and aluminum are all metals and are highly prized in electronics for their excellent conductivity. Silver is actually the most conductive metal, followed closely by copper and gold, with aluminum also being a highly effective, lightweight conductor. The incorrect options all contain at least one non-metallic insulator. Paper, mica, and wood firmly resist the flow of electricity, making those groupings incorrect.
