Which of the following is NOT an ortho or para directing group in electrophilic aromatic substitution reactions?

Step-by-step solution

In electrophilic aromatic substitution reactions, ortho and para directing groups increase electron density at these positions, promoting substitution. Chlorine (-Cl) is a moderately deactivating group due to its strong -I effect and does not increase electron density on the ortho and para positions, unlike the other groups listed.
