In the reaction $\mathrm{HSO}_{4}^{-}(\mathrm{aq})+\mathrm{OH}^{-}(\mathrm{aq}) \rightleftharpoons \mathrm{SO}_{4}^{2-}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}(\ell)$, the conjugate acid-base pairs are
(a)$\mathrm{HSO}_{4}^{-}$and $\mathrm{SO}_{4}^{2-} ; \mathrm{H}_{2} \mathrm{O}$ and $\mathrm{OH}^{-}$
(b)$\mathrm{HSO}_{4}^{-}$and $\mathrm{H}_{3} \mathrm{O}^{+} ; \mathrm{SO}_{4}^{2-}$ and $\mathrm{OH}^{-}$
