(A) Lewis base is a substance that can donate a lone pair of electrons. In $PF_{3}$,the phosphorus atom has one lone pair of electrons. Therefore,$PF_{3}$ can act as a Lewis base. In contrast,$SF_{4}$,$SiF_{4}$,and $BF_{3}$ are Lewis acids because they have vacant orbitals or are electron-deficient and can accept electron pairs.
