4-Cyanobenzoic acid has deactivating group at para position which shows -R and -I effect which enhance the acidic strength of carboxylic acid. So option D is correct that is 4-Cyanobenzoic acid is strongest acid among them. Among all, 4-Cyanobenzoic acid has pka value =3.55, 4-bromobenzoic acid has pKa=3.96,Benzoic acidpKa=4.2 and 4-Methoxybenzoic acid has pKa= 4.50. So correct order is D>A>C>B.
