An organic compound '$\mathrm{A}$' on reaction with ${\mathrm{NH}}_3$ followed by heating gives compound $\mathrm{B}$. Which on further strong heating gives compound $\mathrm{C}$ $\left({\mathrm{C}}_8{\mathrm{H}}_5{\mathrm{NO}}_2\right)$. Compound $\mathrm{C}$ on sequential reaction with ethanolic $\mathrm{KOH}$, alkyl chloride and hydrolysis with alkali gives a primary amine. The compound $\mathrm{A}$ is

The correct stability order of the following diazonium salt is

Given below are two statements: one is labelled as Assertion $\left(\mathrm{A}\right)$ and the other is labelled as Reason $\left(\mathrm{R}\right)$.

Assertion $\left(\mathrm{A}\right)$ : Experimental reaction of ${\mathrm{CH}}_3\mathrm{Cl}$ with aniline and anhydrous ${\mathrm{AlCl}}_3$ does not give $\mathrm{o}$ and $\mathrm{p}$-methylaniline.

Reason $\left(\mathrm{R}\right)$ : The $-{\mathrm{NH}}_2$ group of aniline becomes deactivating because of salt formation with anhydrous ${\mathrm{AlCl}}_3$ and hence yields $\mathrm{m}$-methyl aniline as the product.
