(A) The chemical formula of pyrophosphoric acid is $H_4P_2O_7$.Its structure consists of two $P$ atoms linked by an oxygen bridge $(P-O-P)$.Each $P$ atom is double-bonded to an oxygen atom $(P=O)$ and bonded to two hydroxyl groups $(-OH)$.Counting the bonds:- Total $\sigma$ bonds: There are $4$ $P-OH$ bonds,$2$ $P=O$ bonds (each has $1$ $\sigma$),$1$ $P-O-P$ bridge (which has $2$ $\sigma$ bonds),and $4$ $O-H$ bonds. Total $\sigma$ bonds = $4 + 2 + 2 + 4 = 12$.- Total $\pi$ bonds: There are $2$ $P=O$ bonds,each containing $1$ $\pi$ bond. Total $\pi$ bonds = $2$.- The ratio of $\sigma$ to $\pi$ bonds = $\frac{12}{2} = 6$.Therefore,the correct option is $A$.

The ratio of $\sigma$ and $\pi$ bonds present in pyrophosphoric acid $(H_4P_2O_7)$ is $......$.
