Why does presence of a nitro group make the benzene ring less reactive in comparison to the unsubstituted benzene ring. Explain.

Options

1. AThe nitro group is a strong electron-donating group that enhances the reactivity of the benzene ring.
2. BThe nitro group is a powerful electron-withdrawing group that reduces the electron density on the benzene ring
3. CThe nitro group has no significant effect on the reactivity of the benzene ring.
4. DThe nitro group acts as a resonance donor, increasing the electron density on the benzene ring.
