Match List $I$ with List $II$:

List $I$ (Amines)	List $II$ $(pK_{b})$
$A$. Aniline	$I$. $3.25$
$B$. Ethanamine	$II$. $3.00$
$C$. $N$-Ethylethanamine	$III$. $9.38$
$D$. $N,N$-Diethylethanamine	$IV$. $3.29$

Choose the correct answer from the options given below:

Identify $X$ and $Y$ of the following reaction sequence.

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$: Experimental reaction of $CH_{3}Cl$ with aniline and anhydrous $AlCl_{3}$ does not give $o-$ and $p-$methylaniline.
Reason $(R)$: The $-NH_{2}$ group of aniline becomes deactivating because of salt formation with anhydrous $AlCl_{3}$ and hence yields $m-$methylaniline as the product.
In the light of the above statements,choose the most appropriate answer from the options given below.
