Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The position of the incoming group is determined by the nature of the group present in the monosubstituted benzene ring.
There can be two types of a monosubstituted group on benzene ring viz. electron donating and an electron withdrawing group.
Electron donating group will attack at ortho and para position whereas the electron withdrawing group will attack meta position.
