Solution
The correct option is B graphite
Graphite has a two-dimensional sheet structure. Each carbon atom is in sp2-hybridized state and is linked to other three carbon atoms in: a hexagonal planar structure. After forming three C-C bonds, each carbon atom is left with one electron in its p-orbital. This electron then overlaps with the other to form a π−bond. The π−electrons are free to move throughout the layers, so graphite is a good conductor of electricity.Hence option B is correct.
