Solution

The correct option is A $H_{2} {C O}_{3}, {C H}_{3} C O O H, H_{2} {S O}_{4}$
Strong acid means weak conjugate base.
Strength of Conjugate base order: ${H S O}_{4}^{2 -} < {C H}_{3} C O O^{-} < {H C O}_{3}^{-}$
Strength of acidity: ${H_{2} S O}_{4} > {C H}_{3} C O {O H} > {H_{2} C O}_{3}$
