JEE Main Chemistry question

In the following compounds, the order of acidic strength is: (I) phenol, (II) -cresol, (III) -nitrophenol, (IV) -nitrophenol-type structures as drawn

(A)III > IV > I > II
(B)I > IV > III > II
(C)II > I > III > IV
(D)IV > III > I > IICorrect

Answer: (D)

Solution

Electron-withdrawing nitro groups increase phenol's acidity (more so from the para position, via resonance, than from the meta position, inductively only), while the
