(C) The structure of $H_3PO_3$ (phosphorous acid) contains one $P=O$ bond,two $P-OH$ bonds,and one $P-H$ bond.$1$. Lone pairs $(x)$: The oxygen atom in the $P=O$ bond has $2$ lone pairs. Each of the two $-OH$ oxygen atoms has $2$ lone pairs. Total lone pairs $x = 2 + 2 + 2 = 6$.$2$. Sigma bonds $(y)$: There are $5$ single bonds ($P-H$,two $P-O$ in $P-OH$,and two $O-H$ in $P-OH$) and one sigma bond in the $P=O$ double bond. Total sigma bonds $y = 5 + 1 = 6$.$3$. Pi bonds $(z)$: There is one $P=O$ double bond,which contains one $\pi$ bond. So,$z = 1$.Calculating the sum: $x + y + z = 6 + 6 + 1 = 13$.Therefore,the correct option is $C$.

Calculate $x + y + z$ for $H_3PO_3$ acid,where $x$ is the number of lone pairs,$y$ is the number of $\sigma$ bonds,and $z$ is the number of $\pi$ bonds.
