Which of the following statements is $NOT$ correct regarding Hofmann's exhaustive alkylation?

How many moles of ethyl bromide are required for the formation of $1 \ mole$ of $N,N$-diethylethanamine from ethylamine?

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.

Choose the correct option.
