Generally, boiling points increase as the molecular weight of the compound increases. Among the given options, Pb has the highest atomic weight, and therefore it is expected to have the highest boiling point. Additionally, the size of the Pb atom allows it to form strong intermolecular forces, resulting in a higher boiling point than the other options.
