What is the best conductor among the following materials?

Copper is renowned for its excellent electrical conductivity and is the standard material used for most electrical wiring. It has a very low electrical resistance, allowing electrons to flow freely from atom to atom. While aluminum is also a good conductor and is often used in power transmission lines due to its light weight and lower cost, copper is inherently a better electrical conductor. Carbon and silicon are not good conductors; carbon is often used for manufacturing resistors, and silicon is a semiconductor.
