0Assertion (A): Simple aryl halides (e.g., \( \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{Cl} \) ) are inert to nucleophilic reagents, but 2,4-dinitrochlorobenzene reacts with \( \left(\mathrm{CH}_{3}\right)_{2} \mathrm{NH} \) at room temperature to give
Reason (R): The presence of strongly electron-attracting substituents (in 0 - and p-positions or both), activates the chloro group in 2,4-dinitrochlorobenzene.
(A) Both A and R are true and R is the correct explanation of A.br(B) Both A and R are true, but R is not the correct explanation of A.
(C) A is true, but R is false.
(D) A is false, but R is true.
(E) Both A and R are false.
