Which one of the following is not an electrophile?

Electrophilic substitutions are characteristic reaction of aromatic compounds. In this reaction hydrogen of the aromatic ring is replaced by an electophile because hydrogen in the form of HR is very good leaving group. -COOH and -SO_3H are also good leaving groups when they are present either at ortho or at para to the highly activating groups like -NH_2 and -OH. Which one of the following compounds will be most unreactive towards electrophilic substitution reaction?

Among the following which is less reactive towards electrophilic substitution reactions

The typical reaction of benzene and other aromatic compounds is electrophilic substitution. Presence of electron donating group activates the ring towards electrophilic substitution, while presence of electron withdrawing group deactivates the ring towards electrophilic substitution but at the same time activates the ring towards nucleophilic substitution. Some groups are predominantly meta directing and all of these are deactivating. Except halogen, most of the o- and p- directing groups are activating groups.
