Correct answer: C. (A), (C) only

In all these molecules O _ 2 andNO , is stabilized by removal of electrons because it is having electrons in the anti-bonding orbital. And thus removal of electron from the anti bonding orbital, increases the bond order of O _ 2 andNO . And thus is becomes more stable after removal of electrons. Bond order of O _ 2 ^ + is 2 . 5 and it is more than that of O _ 2 which is having bond order as 2 . Similarly Bond order of NOis2 . 5andthatof NO ^ + is3 .
