    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).
