Solution
The correct option is B Graphite
Graphite is an allotropic form of carbon. Carbon has four valence electrons, this means it can accommodate four more electrons and form four covalent bonds. In case of graphite, the carbon atom is linked with three neighbouring carbon atoms, thus forming a hexagonal arrangement of atoms. As carbon can form four covalent bonds, one of the carbon electron is unpaired and this free electron is available for conduction the of electricity. All other allotropic forms of carbon does not conduct electricity.
