Options

A.
B.
C.
D.

Answer

B

Explanation

When two different groups are present on a benzene ring the more powerful activating group generally determines the outcome of the reaction `-CH_(3)` is moderately activating while `-CH_(3)` is weakly activating. Thus, `-OCH_(3)` group determines the outcome of the reaction for `-OCH_(3)`, `-I_("effect")` follows the order :`ogtmgtp` while `+R_("effect")` follows the order: `ocongp`. Always remember that any kind of resonance effect never operates at meta position. Hence, substitution occurs mainly at the position para to the `-OCH_(3)` which is further activated by the ortho/para directing influence of `-CH_(3)` since steric effect are important in aromatic substitutions, substitution does not occur to an appreciable extent between meta substituents if another position is open.
