The presence of a halogen on the benzene ring in a nitration reaction leads to:

1. Direct nitro group to come at meta and deactivate the ring due to –I effect of halogen.
2. Direct nitro group to come at ortho and para position and deactivate the ring due to –I effect of halogen.
3. Direct nitro group to come at meta and activate the ring toward nitration reaction.
4. Nitration reaction does not take place due to deactivation caused by –I effect of halogen.
