Given below are two statements:
In the light of the above statements, choose the most appropriate answer from the options given below:
| I: | The acidic strength of monosubstituted nitrophenol is higher than phenol because of electron withdrawing nitro group. |
| II: | o-Nitrophenol, m-nitrophenol and p-nitrophenol will have same acidic strength as they have one nitro group attached to the phenolic ring. |
| 1. | I is incorrect but II is correct. |
| 2. | Both I and II are correct. |
| 3. | Both I and II are incorrect. |
