Answer 1

The correct option is A conductor

Metal is a good conductor of electricity because the electrons are free to move in a network of metal atom. So because of the "Sea of Electrons", these electrons do not belong to just one atom but move freely about the metal's network which makes them great conductors of heat and electricity so iron is a metal conducting electricity.
