Doubt in Aromatic Reaction

For questions no. 8
Why is Option B not one of the answers?

Because it is not electron withdrawing group but electron donating group.
Other group are electron withdrawing because of =O attached to them.

Even option B has =O

Sorry I misread your question.
I thought it was A.
Possible explantion for B is lone pair of sulphur involve in resonance with -Ph.
