Which of the following statements is correct?

Graphite has hexagonal carbon crystals, which are smooth and slippery rather than rigid. However, when it is dry and vacuumed, it is not slippery.
Because of the delocalization of electrons inside the carbon layers, graphite is a good electrical conductor. We refer to this phenomena as aromaticity. This characteristic is similar to that of metals. Therefore, we might claim that it has metallic properties.
Adsorption does not cause the layers of the graphite crystals to slide.
