The product $(B)$ is:

$A$ given nitrogen-containing aromatic compound $A$ reacts with $Sn/HCl,$ followed by $HNO_2$ to give an unstable compound $B$. $B,$ on treatment with phenol,forms a beautiful coloured compound $C$ with the molecular formula $C_{12}H_{10}N_2O.$ The structure of compound $A$ is

Match List-$I$ with List-$II$ :

List-$I$	List-$II$
$a$. Gabriel synthesis	$i$. Benzaldehyde
$b$. Kolbe synthesis	$ii$. Ethers
$c$. Williamson synthesis	$iii$. Primary amines
$d$. Etard reaction	$iv$. Salicylic acid

Choose the correct answer from the options given below :

Match each of the compounds in Column $I$ with its characteristic reaction$(s)$ in Column $II$.

Column $I$	Column $II$
$A$. $CH_3CH_2CH_2CN$	$p$. Reduction with $Pd-C/H_2$
$B$. $CH_3CH_2OCOCH_3$	$q$. Reduction with $SnCl_2/HCl$
$C$. $CH_3-CH=CH-CH_2OH$	$r$. Development of foul smell on treatment with chloroform and alcoholic $KOH$
$D$. $CH_3CH_2CH_2CH_2NH_2$	$s$. Reduction with diisobutylaluminium hydride $(DIBAL-H)$
	$t$. Alkaline hydrolysis

Given below are some nitrogen-containing compounds. Each of them is treated with $HCl$ separately. $1.0 \ g$ of the most basic compound will consume $........$ $mg$ of $HCl$. ($Given$ molar mass in $g \ mol^{-1}$: $C:12, H:1, O:16, Cl:35.5$)

$Ph-NH_2$ $\xrightarrow{CH_3Cl \ (2 \ mole)} (A)$ $\xrightarrow{Ph-N_2^+ Cl^-} (B) \ (\text{major})$
