Which of the following is a good conductor of electricity?(A) Diamond(B) Graphite(C) Both A and B(D) None of the above
The correct answer is (B) Graphite.
Graphite is a good conductor of electricity due to its structure, which includes delocalized electrons that can move freely. Diamond, on the other hand, is a poor conductor of electricity because it lacks free electrons; its carbon atoms are all involved in strong covalent bonds in a rigid lattice structure.
