The correct order of energies of molecular orbitals of `N_2` molecule, is:

Options

A. `sigma 1s lt sigma^** 1s lt sigma 2s lt sigma^** 2s lt sigma 2p_z lt (pi 2 p_z = pi 2pi_y) lt (pi^** 2p_x = pi^** 2p_y) lt sigma^** 2p_z`
B. `sigma 1s lt sigma^** 1s lt sigma 2s lt sigma^** 2s lt sigma 2p_z lt sigma^** 2p_z lt (pi 2 p_z = pi 2pi_y) lt (pi^** 2p_x = pi^** 2p_y)`
C. `sigma 1s lt sigma^** 1s lt sigma 2s lt sigma^** 2s lt (pi 2 p_z = pi 2pi_y) lt (pi^** 2p_x = pi^** 2p_y)lt sigma 2p_z lt sigma^** 2p_z`
D. `sigma 1s lt sigma^** 1s lt sigma 2s lt sigma^** 2s lt (pi 2 p_z = pi 2pi_y) lt sigma 2p_z lt (pi^** 2p_x = pi^** 2p_y) lt sigma^** 2p_z`
