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

Identify the correct statement for the below given transformation.

An organic compound $'\mathrm{A}'$ contains nitrogen and chlorine. It dissolves readily in water to give a solution that turns litmus red. Titration of compound $'\mathrm{A}'$ with standard base indicates that the molecular weight of $'\mathrm{A}'$ is $131 \pm 2$. When a sample of $'\mathrm{A}'$ is treated with aq. $\mathrm{NaOH}$, a liquid separates which contains $\mathrm{N}$ but not $\mathrm{Cl}$. Treatment of the obtained liquid with nitrous acid followed by phenol gives orange precipitate. The compound $'\mathrm{A}'$ is :

Match List I with List II.

Choose the correct answer from the options given below:

The correct sequential order of the reagents for the given reaction is

The correct stability order of the following diazonium salt is

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : Experimental reaction of $\mathrm{CH}_{3} \mathrm{Cl}$ with aniline and anhydrous $\mathrm{AlCl}_{3}$ does not give $o$ and $p$-methylaniline.

Reason (R): The $-\mathrm{NH}_{2}$ group of aniline becomes deactivating because of salt formation with anhydrous $\mathrm{AlCl}_{3}$ and hence yields $m$-methyl aniline as the product.

In the light of the above statements, choose the most appropriate answer from the options given below :
