Which of the following amines will not give $N_2$ gas on treatment with nitrous acid $(NaNO_2 + HCl)$?

Which one of the following methods is neither meant for the synthesis nor for separation of amines?

Given below are two statements:
Statement-$I$ : Oxidation of $p$-nitrotoluene with acidic $KMnO_4$ gives an acid that is stronger than benzoic acid.
Statement-$II$ : Reduction of $p$-nitrotoluene with $Sn/HCl$ followed by neutralization gives an amine that is more basic than aniline.
In light of the above statements, choose the most appropriate answer from the options given below.

Match the Compounds (List-$I$) with the appropriate Catalyst/Reagents (List-$II$) for their reduction or conversion into corresponding amines.

List-$I$ (Compounds)	List-$II$ (Catalyst/Reagents)
$A$. $R-CONH_2$	$I$. $NaOH$ (aqueous)
$B$. $C_6H_5NO_2$	$II$. $H_2 / Ni$
$C$. $R-C \equiv N$	$III$. $LiAlH_4, H_2O$
$D$. $N$-alkylphthalimide	$IV$. $Sn,HCl$

Choose the correct answer from the options given below:
