(A) According to Molecular Orbital Theory $(M.O.T)$,the electronic configuration of oxygen species is as follows:$1$. For $O_2$ ($16$ electrons): $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2 = \pi 2p_y^2, \pi^* 2p_x^1 = \pi^* 2p_y^1$. The number of antibonding electrons is $2 + 2 + 1 + 1 = 6$.$2$. For $O_2^-$ ($17$ electrons): $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2 = \pi 2p_y^2, \pi^* 2p_x^2 = \pi^* 2p_y^1$. The number of antibonding electrons is $2 + 2 + 2 + 1 = 7$.$3$. For $O_2^{2-}$ ($18$ electrons): $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2 = \pi 2p_y^2, \pi^* 2p_x^2 = \pi^* 2p_y^2$. The number of antibonding electrons is $2 + 2 + 2 + 2 = 8$.Thus,the number of antibonding electrons in $O_2^-$,$O_2$,and $O_2^{2-}$ are $7, 6, 8$ respectively.

In $O_2^-$,$O_2$,and $O_2^{2-}$,the total number of antibonding electrons respectively are:
