Answer: C
Notes: Graphite, an allotrope of carbon, has the chemical formula 'C'. It consists of layers of carbon atoms that are arranged in a hexagonal lattice. Other allotropes include diamond and fullerene. Due to its special structure, each carbon atom in graphite is connected to only three other carbon atoms, which results in one free electron that contributes to its electrical conductivity.
