							Generally, the elements possess odd number of electrons will have unpaired electrons.

So, forKO2​there would be 35 electrons(19+8×2)

ForAlO2−​there would be 20 electrons(13+8×2+1)(for negative charge)

ForBaO2​there would be 72 electrons(56+16)

ForNO2+​there would be 12 electrons(7+8×2−1)(for positive charge)

So onlyKO2​is having odd number of electrons so it is having unpaired electrons.

KO2​has(K++O2−​)structure having one unpaired electron due to presence of superoxide ion(O2−​ion)in it, which is paramagnetic.

Hence option A is correct.
