NH3 because it can form hydrogen bonding while PH3 can't so NH3 will have the strongest intermolecular forces which means its boiling point will be highest

NH3 would have a higher boiling point because the nitrogen forms bonds with H. Remember that for intermolecular forces it goes from Van der Waals, dipole-dipole to H-binding as the strongest.
