Hint: In physics and engineering, a conductor is an entity or form of material that lets charging flow in one or more directions (electrical current). Metal elements are the rising conductors of electricity. Current energy is produced by the passage of negative electrons, positively filled holes, and in certain situations positive or negative ions.

Complete step by step solution:
Electric current will flow freely in a conductor, but cannot flow freely in an insulator. Metals such as copper are typical of conductors, whereas the bulk of non-metallic compounds are considered to be strong insulators, providing exceptionally high load flow resistance. "The conductor" means the unbound and unrestricted passage of the exterior electrons of the atoms. Most atoms are closely bound and insulator to their electrons. Copper is completely free of valence electrons and actively repels one another. Any outside force that drives one of these electrons can trigger other "domino fashion" electrons to repulsive the carrier.
Three other carbon atoms are linked to one carbon atom in graphite. One carbon electron is already free. Thanks to this free valence graphite electron becomes an electrical conductor.

Hence, option B is the correct option.

Note: Graphite, with its atoms formed in a hexagonal form, is a crystalline part of carbon. This is in this shape of course and in normal terms, the most durable source of carbon. It turns into diamond at extreme pressures and temperatures. In pencils and lubricants, graphite is used. Air and power are strong conductors. The strong conductivity allows it to be practical with electrodes, batteries and solar panels for electronic devices.
