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 \(m\)-methyl aniline as the product. In the light of the above statements, choose the most appropriate answer from the options given below.

1. A Both \((A)\) and \((R)\) are true and \((R)\) is the correct explanation of \((A)\).
2. B Both \((A)\) and \((R)\) are true but \((R)\) is not the correct explanation of \((A)\).
3. C \((A)\) is true, but \((R)\) is false.
4. D \((A)\) is false, but \((R)\) is true.
