If \( K_{1} \) and \( K_{2} \) are the first and second ionization constants of \( \mathrm{H}_{2} \mathrm{CO}_{3} \) and \( K_{1} \gg K_{2} \), then the incorrect relation(s) is/are
(a) \( \left[\mathrm{H}^{+}\right]=\left[\mathrm{HCO}_{3}^{-}\right] \)
(b) \( \left[\mathrm{H}^{+}\right]=\sqrt{\mathrm{K}_{1} \cdot\left[\mathrm{H}_{2} \mathrm{CO}_{3}\right]} \)
(c) \( K_{2}=\left[\mathrm{CO}_{3}{ }^{2-}\right] \)
(d) \( \left[\mathrm{H}^{+}\right]=2 \cdot\left[\mathrm{CO}_{3}{ }^{2-}\right] \)
