Given the following \( K_{a} \) values, determine which species is the strongest base. \( \mathrm{HSO}_{4}^{-}=1.2 \times 10^{-2}, \mathrm{H}_{2} \mathrm{PO}_{4}^{-}=6.3 \times 10^{-8}, \mathrm{HCO}_{3}^{-}=4.7 \times 10^{-11} \)
(a) \( \mathrm{CO}_{3}^{2-} \)
(b) \( \mathrm{H}_{2} \mathrm{SO}_{4} \)
(c) \( \mathrm{SO}_{4}^{2-} \)
(d) \( \mathrm{HPO}_{4}^{2-} \)
