(C) The electronic configuration of $O_2^+$ ($13$ electrons) is: $KK \sigma 2s^2 \sigma^* 2s^2 \sigma 2pz^2 (\pi 2px^2 = \pi 2py^2) (\pi^* 2px^1)$. It has one unpaired electron,so it is paramagnetic.The electronic configuration of $O_2$ ($16$ electrons) is: $KK \sigma 2s^2 \sigma^* 2s^2 \sigma 2pz^2 (\pi 2px^2 = \pi 2py^2) (\pi^* 2px^1 = \pi^* 2py^1)$. It has two unpaired electrons,so it is paramagnetic.Since both $O_2^+$ and $O_2$ contain unpaired electrons in their $\pi^*$ antibonding molecular orbitals,both are paramagnetic.
