(B) $1$. The total number of valence electrons in $PO_4^{3-}$ is $5 + (4 	imes 6) + 3 = 32$.$2$. The structure of $PO_4^{3-}$ involves one $P=O$ double bond and three $P-O$ single bonds in its Lewis structure. The total number of bonds is $5$. The number of $P-O$ linkages is $4$. Bond order = $\frac{	ext{Total number of bonds}}{	ext{Number of resonating bonds}} = \frac{5}{4} = 1.25$. Thus,statement $A$ is true.$3$. The formal charge on each oxygen atom is calculated as: $\frac{	ext{Total charge}}{	ext{Number of oxygen atoms}} = \frac{-3}{4} = -0.75$. Thus,statement $B$ is true.$4$. $PO_4^{3-}$ has four equivalent resonance structures corresponding to the four different positions of the $P=O$ double bond. Thus,statement $C$ is true.
