If the highest occupied molecular orbital (HOMO) is an antibonding molecular orbital, removal of an electron leads to an increase in Bond order thereby increasing the bond strength.

Among the given species, the ones having Antibonding Molecular orbital as the HOMO are \mathrm{NO}, \mathrm{O}_{2}

Hence, the correct answer is Option (3)
