(B) The chemical formula of peroxodisulphuric acid (Marshall's acid) is $H_2S_2O_8$.Its structure consists of two $SO_3$ groups linked by a peroxide linkage $(-O-O-)$.In the structure:- There are $2$ $S=O$ double bonds per sulfur atom, contributing $2$ $\pi$ bonds each, totaling $4$ $\pi$ bonds.- Counting the $\sigma$ bonds: $4$ $S=O$ bonds, $2$ $S-OH$ bonds, $2$ $O-H$ bonds, $2$ $S-O$ bonds (to peroxide oxygen), and $1$ $O-O$ bond.- Total $\sigma$ bonds = $4 + 2 + 2 + 2 + 1 = 11$.- Total $\pi$ bonds = $4$.Thus, the number of $\sigma$ and $\pi$ bonds are $11$ and $4$ respectively.

The number of sigma $(\sigma)$ and pi $(\pi)$ bonds in peroxodisulphuric acid are, respectively:
