(B) The electronic configuration of $O_2$ is $KK(\sigma_{2s})^2(\sigma_{2s}^*)^2(\sigma_{2p_z})^2(\pi_{2p_x})^2(\pi_{2p_y})^2(\pi_{2p_x}^*)^1(\pi_{2p_y}^*)^1$. When an electron is added to form $O_2^-$,it enters the lowest energy vacant antibonding molecular orbital,which is $\pi_{2p_x}^*$ (or $\pi_{2p_y}^*$). Thus,the electron is added to the $\pi^*$ molecular orbital.
