# Presence of a nitro group in a benzene ring

$\begin{array}{1 1}(a)\;\text{Deactivates the ring towards electrophilic substitution}\\(b)\; \text{Activates the ring towards electrophilic substitution}\\(c)\;\text{Renders the ring basic}\\(d)\;\text{Deactivates the ring towards nucleophilic substitution}\end{array}$

From the resonating structures of it can be seen that the nitro group with drawn electrons from the rings and hence it deactivates the benzene ring further electrophilic substitution.
Hence (a) is the correct answer.
