Question

Consider the following reactions. $\mathrm{PbCl}_2+\mathrm{K}_2 \mathrm{CrO}_4 \rightarrow \mathrm{~A}+2 \mathrm{KCl}$ (Hot solution) $$ \begin{aligned} & \mathrm{A}+\mathrm{NaOH} \rightleftharpoons \mathrm{~B}+\mathrm{Na}_2 \mathrm{CrO}_4 \\ & \mathrm{PbSO}_4+4 \mathrm{CH}_3 \mathrm{COONH}_4 \rightarrow\left(\mathrm{NH}_4\right)_2 \mathrm{SO}_4+\mathrm{X} \end{aligned} $$ In the above reactions, $\mathrm{A}, \mathrm{B}$ and X are respectively.

Select the correct option:

$\mathrm{Na}_2\left[\mathrm{~Pb}(\mathrm{OH})_2\right], \mathrm{PbCrO} \mathrm{O}_4$ and $\left(\mathrm{NH}_4\right)_2\left[\mathrm{~Pb}\left(\mathrm{CH}_3 \mathrm{COO}\right)_4\right]$

$\mathrm{PbCrO}_4, \mathrm{Na}_2\left[\mathrm{~Pb}(\mathrm{OH})_4\right]$ and $\left[\mathrm{Pb}\left(\mathrm{NH}_3\right)_4\right] \mathrm{SO}_4$

$\mathrm{Na}_2\left[\mathrm{~Pb}(\mathrm{OH})_2\right], \mathrm{PbCrO}_4$ and $\left[\mathrm{Pb}\left(\mathrm{NH}_3\right)_4\right] \mathrm{SO}_4$

$\mathrm{PbCrO}_4, \mathrm{Na}_2\left[\mathrm{~Pb}(\mathrm{OH})_4\right]$ and $\left(\mathrm{NH}_4\right)_2\left[\mathrm{~Pb}\left(\mathrm{CH}_3 \mathrm{COO}\right)_4\right]$
