Solution

The correct option is D Assertion is incorrect and Reason is correct
Alkyl groups like $C_{2} H_{5}$ are electron donating group. They donate the electrons to the compounds which they attach and acts as a Lewis base.
The electron donating group acts as the ortho-meta directing group. Thus Assertion is incorrect.
The groups like $N O_{2}$ acts as electron withdrawing group and thus activate the meta position by directing the incoming electrons towards meta position. Thus the Reason is correct.
Hence option D is right.
