The correct one among the following statements about $N_2$ is

$\begin{array}{1 1}(a)\;\text{it has two unpaired electrons}\\(b)\;\text{the bond order is 2.5}\\(c)\;\text{the highest occupied molecular orbital is }3\sigma_g\\(d)\;\text{the lowest occupied molecular orbital is }2p\pi_x^*\end{array}$

Can you answer this question?

$N_2$ bond order is 3
It has no unpaired electrons.
$N_2$ electronic configuration :$(\sigma 1s)^2 < (\sigma ^*1s)^2 < (\sigma 2s)^2 < (\sigma^* 2s)^2 < (\pi 2p_x^2=\pi 2p_y^2) < (\sigma 2p_z)^2$
**** is $\sigma 2p_z$
Lumo is $2p\pi_x^*,2p\pi_y^*$
Hence (d) is the correct answer.
