Solution
The correct option is C It is a good conductor of electricity
Graphite is an allotrope of carbon. It is a covalent compound. Graphite is soft in nature.
Graphite is made up of two-dimensional sheets having hexagonal closed structure.
Each carbon atom creates a covalent bond with three other carbon atoms, and the fourth electron establishes a bond.
The atoms' weak van der Waals forces hold the multiple layers together. The electrons are mobile and delocalized across the entire sheet.
As a result, graphite is an excellent electrical conductor and is used in making electrodes.
Hence, option (C) is the correct option.
