Best answer

Answer: 4. Diamond is \(sp^3\) hybridised and graphite is \(sp^2\) hybridized.

Key idea: diamond and graphite are both covalent forms of carbon with different hybridisation.

Diamond: every C is \(sp^3\) in a 3D network. Graphite: every C is \(sp^2\) in 2D layers. Option 4 is correct.
