Chemical Bonding And Molecular Structure

The pairs among

$\mathrm{A}=\left[\mathrm{SO}_3^{2-}, \mathrm{CO}_3^{2-}\right], \mathrm{B}=\left[\mathrm{O}_2^{2-}, \mathrm{F}_2\right], \mathrm{C}=\left[\mathrm{CN}^{-}, \mathrm{CO}\right], \mathrm{D}=\left[\mathrm{NH}_3, \mathrm{H}_3 \mathrm{O}^{+}\right]$and $\mathrm{E}=\left[\mathrm{MnO}_4^{2-}, \mathrm{CrO}_4^{2-}\right]$ that do not have similar Lewis dot structure are
