According to molecular orbital theory, the paramagnetism of ${O_2}$ molecule is due to presence of
Unpaired electrons in the bonding $\sigma $ molecular orbital
Unpaired electrons in the antibonding $\sigma $ molecular orbital
Unpaired electron in the bonding $\pi $ molecular orbital
Unpaired electrons in the antibonding $\pi $ molecular orbital
