Solution

The correct option is D $O_{2}^{2 -}$
$O_{2}^{2 -}$ all the molecular orbitals are completely filled except $σ^{*} 2 p_{z}$ and paired electrons. Therefore it is diamagnetic.

$N O$ has 15 electrons, species having odd electrons are always paramagnetic.

$O_{2}^{+}$ has 15 electrons.

$O_{2}$ molecule has 2 unpaired electrons as per MOT making it paramagnetic.
