Solution

The correct option is C $H_{2}$
For $H_{2}$ ,

$1 s^{2} * 1 s^{2}$
For $H_{2}^{-}$ ,
$1 s^{2} * 1 s^{2} 2 s^{1}$
For $H_{2}^{+}$ ,
$1 s^{2} * 1 s^{1}$
For $H e_{2}^{+}$ ,
$1 s^{2} * 1 s^{1}$
Diamagnetic species are those which do not contain unpaired electrons. In the given species, only $H_{2}$ has even no. of electrons.
