The reaction of a given compound with ${\mathrm{NaNO}}_2$ and $\mathrm{HCl}$ forms $\mathrm{X}$ as the major product. What is true about $\mathrm{X}$?

In the above reactions:
$\left(\mathrm{a}\right)$ $\mathrm{X}$ and $\mathrm{Y}$ are isomers.
$\left(\mathrm{b}\right)$ $\mathrm{X}$ and $\mathrm{Y}$ are $1°$ amines.
$\left(\mathrm{c}\right)$$\mathrm{X}$ and $\mathrm{Y}$ are homologous.
$\left(\mathrm{d}\right)$ $\mathrm{Y}$ is the bromo derivative of $\mathrm{X}$.

The correct statements are:

${\mathrm{C}}_6{\mathrm{H}}_5-{\mathrm{NO}}_2\underset{{\mathrm{NH}}_4\mathrm{Cl}}{\overset{\mathrm{Zn} \mathrm{dust}}{\to }}\mathrm{A} \underset{\mathrm{conc}. \mathrm{HCl}}{\overset{\mathrm{cold}}{\to }}\mathrm{B}$ 

$\mathrm{A}$ and $\mathrm{B}$ respectively are:
