(D) Total number of electrons in $O_2^{2-} = 18$.The molecular orbital electronic configuration of $O_2^{2-}$ is:$\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2 = \pi 2p_y^2, \pi^* 2p_x^2 = \pi^* 2p_y^2$.Bond order is calculated using the formula: $BO = \frac{N_b - N_a}{2}$,where $N_b$ is the number of bonding electrons and $N_a$ is the number of antibonding electrons.Here,$N_b = 10$ and $N_a = 8$.Therefore,$BO = \frac{10 - 8}{2} = 1$.

The bond order in $O_2^{2-}$ is
