At $$25^\circ\text{C}$$ the $$K_a$$ values of $$\text{HPO}_4^{2-}$$ and $$\text{HSO}_3^-$$ are $$4.8 \times 10^{-13}$$ and $$6.3 \times 10^{-8}$$ respectively. Which of the following is correct?

$$\text{HPO}_4^{2-}$$ is a stronger acid than $$\text{HSO}_3^-$$ and $$\text{PO}_4^{3-}$$ is a weaker base than $$\text{SO}_3^{2-}$$

$$\text{HPO}_4^{2-}$$ is a weaker acid than $$\text{HSO}_3^-$$ and $$\text{PO}_4^{3-}$$ is a weaker base than $$\text{SO}_3^{2-}$$

$$\text{HPO}_4^{2-}$$ is a weaker acid than $$\text{HSO}_3^-$$ and $$\text{PO}_4^{3-}$$ is a stronger base than $$\text{SO}_3^{2-}$$

$$\text{HPO}_4^{2-}$$ is a stronger acid than $$\text{HSO}_3^-$$ and $$\text{PO}_4^{3-}$$ is a stronger base than $$\text{SO}_3^{2-}$$
