Presence of a nitro group in a benzene ring

Presence of a nitro group in a benzene ring
  1. activates the ring towards electrophilic substitution
  2. renders the ring basic
  3. deactivates the ring towards nucleophilic substitution
  4. deactivates the ring towards electrophilic substitution

Solution

$-\mathrm{NO}_2$ group shows $-\mathrm{M}$ effect, so withdraws the electron density from the ring and hence deactivate the ring towards electrophilic aromatic substitution. Hence, (D) is correct.
