Solution

The correct option is B III > I > II
B
Nitro group is an electron withdrawing group which increases the acidic strength as it stabilizes the anion formed which is why III is more acidic than I. Whereas methyl group is an electron donating group so why decreases the acidic strength as it destabilizes the anion formed.So why II is the least acidic.
