Ortho nitrophenol is more acidic than ortho methoxy phenol because:

1. The NO2-group increases the electron density in phenol while the methoxy group decreases the electron density in phenol
2. The nitro-group is an electron-withdrawing group while the methoxy group is an electron-releasing group
3. The methoxy-group is an electron-withdrawing group while the nitro group is an electron-releasing group
4. None of the above
