Graphite is an allotrope of carbon (C), which has a melting point of about 3600 °C. Graphite is a good conductor and soft material. The density of graphite is less than that of a diamond.

Carbon is found in nature in the form of three isotopes, namely carbon-12, carbon-13, and carbon-14, all of them have 6 protons in their nucleus, but the number of neutrons is different in each, i.e., 6, 7, and 8 respectively.

The tough, porous, and black substance, and almost pure form of carbon is coke. It is obtained from heating coal in the absence of air, and it is widely used as a fuel and as a reducing agent in industries. Coke is used in the production of iron and steel in blast furnaces, and it is also used as a fuel in power plants and cement kilns. The other options listed are also hydrocarbons derived from coal, but they have different properties and uses.

Diamond is not a good conductor of electricity because the carbon atoms in diamond are linked together by covalent bonds. Hence free electrons are not available in diamonds for the conduction of electricity.
