Which of the following order is correct for boiling point?

Phosphine $\left({\mathrm{PH}}_3\right)$ has a lower boiling point than ammonia .$\left({\mathrm{NH}}_3\right)$

Strong intermolecular hydrogen bonds between$\left({\mathrm{NH}}_3\right)$  molecules are formed. However, bigger $\left({\mathrm{PH}}_3\right)$ molecules cannot establish hydrogen bonds amongst themselves due to their lower electronegativity. Unlike $\left({\mathrm{PH}}_3\right)$, where hydrogen bonds are absent, $\left({\mathrm{NH}}_3\right)$ does have hydrogen bonds. $\left({\mathrm{NH}}_3\right)$ has a greater boiling point than $\left({\mathrm{PH}}_3\right)$ as a result.

Hence, option A is correct.
