1. III < I < II
2. III < II < I
3. II < I < III
4. II < III < I

The correct statement regarding the basicity of arylamines is

1. arylamines are generally more basic than alkylamines because of aryl group
2. arylamines are generally more basic than alkylamines, because the nitrogen atom in arylamines is sp-hybridised
3. arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalised by interaction with the aromatic ring -electron system
4. arylamines are generally more basic than alkylamines because the nitrogen lone-pair electrons are not delocalised by interaction with the aromatic ring -electron system.
