Solution

The correct option is A $M_{2} O_{3}, M O_{3}, M O_{2}$
$M_{2} O_{3}, M O_{3} a n d M O_{2}$ are paramagnetic due to presence of unpaired electron in their configuration.
But $M_{2} O_{2} a n d M_{2} O$ are diamagnetic due to absence of unpaired electrons as in their configuration all electrons are paired.
