Identify `A` and predict the type of reaction

Options

A. and elimination, addition reaction

B. and cine substitution reaction

C. and cine substitution reaction

D. and substitution reaction

Answer

D

Explanation

Since `-OCH_(3)` is electron - attracting (-I effect), `(I)` is more stable than `(II)` as in the former the negative charge is closer to `- OCH_(3)`.
Since `-OCH_(3)` exerts `- I^(effect)`, (Iv) is more stable than (III).
Thus, the major product is predicted to be m-amine.
It is example of nucleophilic aromatic substitution following elimination - addition mechanism.
