P-nitrophenol is a stronger acid than phenol while p-cresol is a weaker acid. Discuss.

A

`-CH_(3)` group decreases the electron density on oxygen of O-H group making p-cresol a weaker acid

B

`-NO_(2)` group decreases electron density on oxygen of `O - H` group making p-nitrophenol a stronger acid

C

`-CH_(3)` group increases the electron density on oxygen of `O -H` group making release of `H^(+)` easier

D

`-NO_(2)` group increases the electron density on oxygen of `O - H` group making release of `H^(+)` easier .
