Solution
The correct option is DSilver>Copper>Steel>Plastic Conductors are materials that allow free flow of electrons. These are elements which have electric charges in the form of electrons that are comparatively free to move along the material. Plastic is an electrical insulator, and the other three are electrical conductors. The correct order for electrical conductivity is Silver>Copper>Steel>Plastic
