Answer:
Correct Answer: 33.
$\mathrm{A} \rightarrow \mathrm{p}, \mathrm{s} \quad \mathrm{B} \rightarrow \mathrm{p}, \mathrm{q}, \mathrm{r}, \mathrm{t} \quad \mathrm{C} \rightarrow \mathrm{p}, \mathrm{q}, \mathrm{t} \quad \mathrm{D} \rightarrow \mathrm{p}$
Solution:
$\left(\mathrm{CH}_3\right)_2 \mathrm{SiCl}_2+\mathrm{H}_2 \mathrm{O} \longrightarrow\left(\mathrm{CH}_3\right)_2 \mathrm{Si}(\mathrm{OH})_2+2 \mathrm{HCl}$
$3 \mathrm{XeF}_4+6 \mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{XeO}_3+2 \mathrm{Xe}+12 \mathrm{HF}+\frac{3}{2} \mathrm{O}_2$
$\mathrm{Cl}_2+\mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{HCl}+\mathrm{HOCl} \longrightarrow \mathrm{HCl}+\frac{1}{2} \mathrm{O}_2 $
$\mathrm{VCl}_5+\mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{VOCl}_3+2 \mathrm{HCl}$
