Which of the following is the correct statement for ${\mathrm{PH}}_3$?

The atom of nitrogen is more electronegative than the atom of phosphorus. The bound pair of electrons between the $\mathrm{N}$ and $\mathrm{H}$ atoms are drawn to the nitrogen in ${\mathrm{NH}}_3$, and this action is stronger in ${\mathrm{NH}}_3$ than in ${\mathrm{PH}}_3$. As a result, the lone pair of electrons in ${\mathrm{NH}}_3$ can participate in the dative bonding to a greater extent than those in ${\mathrm{PH}}_3$.
