Answer»
 isresonance stabilized , while in `R-O^(Ө)` DUE to +I effect the `R-O^(Ө)` is destabilized . The conjugate base of `CH_(3)NO_(2)` is `overset(Ө)CH_(2)-NO_(2)` which is RESONANCE sbabilized  out of `-underset(..)overset(..)O-H` group whose conjugate base is `-O^(Ө)` and `-underset(|)overset(|)C^(Ө)` because the charge density is less in `-O^(Ө)` than in`-underset(|)overset(|)C^(Ө)` due to greater surface volume available on `-O^(Ө)` than in `-underset(|)overset(|)C^(Ө)`  is more acidic than ROH and `CH_(3)NO_(2)` . Hence choices (a),(b) and (d) are correct while (c) is incorrect.
