Answer
Correct option: B.
Copper
Copper is a good conductor of electricity as it allows the electricity to flow through it easily.
Copper as a connecting wire has very low electrical resistance.
Copper combines several properties that have traditionally made it preferred for most electrical wiring.
It provides good contact surface, is ductile $($is easily bent repeatedly without breaking$)$ and it is not very expensive and is easy to manufacture.
