Which of the following pair of species are paramagnetic as well as have fractional bond order?

${\mathrm{N}}_2^{+}$ and ${\mathrm{N}}_2^{+}$ 

Following is a description of the electrical structure of ${\mathrm{N}}_2$

$N_2:\sigma \left(1s{)}^2{\sigma }^{\ast }\left(1s^2\right)\sigma \right(2s{)}^2{\sigma }^{\ast }(2s{)}^2\pi {\left(2p_x\right)}^2\pi {\left(2p_y\right)}^2\sigma {\left(2p_z\right)}^2$

Hence correct option is A.
