The given statement is False.
O2​ and O2−​ are paramagnetic while   O22−​ is diamagnetic.

If unpaired electrons are present in an ion/molecule, then it is paramagnetic.
If all electrons are paired, then the ion/molecule is diamagnetic

The MO electronic configurations are given.
O2​:KK(σ2s)2(σ∗2s)2(σ2px)2(π2py)2(π2pz)2(π∗2py)1(π∗2pz)1  2 unpaired electrons.

O2−​:KK(σ2s)2(σ∗2s)2(σ2px)2(π2py)2(π2pz)2(π∗2py)2(π∗2pz)1  1 unpaired electron.

O22−​:KK(σ2s)2(σ∗2s)2(σ2px)2(π2py)2(π2pz)2(π∗2py)2(π∗2pz)2  0 unpaired electrons.
