The highest industrial consumption of molecular hydrogen is to produce compound of element :

Consider the following reaction :

$2{\mathrm{HSO}}_4^{-}\left(\mathrm{aq}\right)\frac{\left(1\right) \mathrm{Electrolysis}}{\left(2\right) \mathrm{Hydrolysis}}2{\mathrm{HSO}}_4^{-}+2{\mathrm{H}}^{+}+\mathrm{A}$

The dihedral angle in product $\mathrm{A}$ in its solid phase at $110 \mathrm{K}$ is

Given below are two statements .
Statement $\mathrm{I}$ : In ${\mathrm{CuSO}}_4·5{\mathrm{H}}_2\mathrm{O}, \mathrm{Cu}-\mathrm{O}$ bonds are present.

Statement $\mathrm{II}$ : In ${\mathrm{CuSO}}_4.5{\mathrm{H}}_2\mathrm{O}$, ligands coordinating with $\mathrm{Cu} \left(\mathrm{II}\right)$  ion are $\mathrm{O}$-and $\mathrm{S}$-based ligands.

In the light of the above statements, choose the correct answer from the options given below
