We know that if the unpaired electron is present in the MOT orbitals of a molecule then it will behave as paramagnetic.

\mathrm{N_2, }\textup{ Unpaired electron - 0}

\mathrm{C_2, }\textup{ Unpaired electron - 0}

\mathrm{N_2^+, }\textup{ Unpaired electron - 1}

\mathrm{O_2^{2-}, }\textup{ Unpaired electron - 0}

So, \mathrm{N^+_2} is paramagnetic.

Hence, the correct answer is Option (3).
