In which set of species, are all the species paramagnetic?

Question

In which set of species, are all the species paramagnetic? (A) B2, O2, N2 (B) B2, O2, N2 + (C) B2, F2, O2 (D) B2, O2, Li2

B2 → KK (σ2s)2 (σ* 2s)2 (π2px)1 (π2py)1 Magnetic character - Paramagnetic O2 → KK (σ2s)2 (σ* 2s)2 (σ2pz)2 (π2px)2 (π2py)2 (π* 2px)1 (π*2py)1 Magnetic character - Paramagnetic N2+ → KK (σ2s)2 (σ* 2s)2 (π2px)2 (π2py)2 (σ2pz)1 Magnetic character - Paramagnetic
