Solution

The correct option is A $O_{2}^{2 -} > O_{2} > O_{2}^{+}$ [Paramagnetic moment]
The order $O_{2}^{2 -} > O_{2} > O_{2}^{+}$ [Paramagnetic moment] is a wrong order with respect to the property mentioned.
$O_{2}^{2 -} O_{2} O_{2}^{+}$ contains $0, 2$ and $1$ unpaired electrons respectively. The correct order is $O_{2} > O_{2}^{+} > O_{2}^{2 -}$ .
