(B) According to Molecular Orbital Theory $(MOT)$,the electronic configuration of $O_2$ ($16$ electrons) is:$O_2: (\sigma 1s)^2 (\sigma^* 1s)^2 (\sigma 2s)^2 (\sigma^* 2s)^2 (\sigma 2p_z)^2 (\pi 2p_x)^2 (\pi 2p_y)^2 (\pi^* 2p_x)^1 (\pi^* 2p_y)^1$.Due to the presence of two unpaired electrons in the antibonding $\pi^*$ orbitals,$O_2$ is paramagnetic.$H_2$,$N_2$,and $CO$ have all paired electrons and are diamagnetic.

The paramagnetic molecule at ground state among the following is
