    Given below are two statements : one is labelled as Assertion (a) and the other is labelled as Reason(R).
    Assertion (a) : Experimental reaction of CH3C1 with aniline and anhydrous A1C13 does not give o and p-methylaniline.
    Reason (R) : The - group of aniline becomes deactivating because of salt formation with anhydrous A1C13 and hence yields m-methyl aniline as the product.
    choose the most appropriate answer from the options given below:
    1. (1)Both (a) and (R) are true and (R) is the correct explanation of (a).
    2. (2)Both (a) and (R) are true but (R) is not the correct explanation of (a).
    3. (3)(a) is true, but (R) is false.
    4. (4)(a) is false, but (R) is true.
