Solution

The correct option is D Silver
Plastic, rubber, and wood are poor conductors of electricity and do not allow an electric current to pass through them easily. Thus, they cannot be used to replace copper wire.
Silver and copper are good conductors of electricity and allow the current to pass through them easily.
Hence, Ram can replace copper wire with a silver wire.
