The correct option is D Z=−NHCOCH3,−CH3,−Br
Groups which direct the incoming group to ortho and para positions are called as ortho and para directing groups.
−NHCOCH3,−CH3,−Br are ortho and para directing groups.
The groups which direct the incoming group to meta position are called Meta directing groups.
−NO2,−CN,−COOH are meta directing.
Hence the correct option is d.
