As One Gains Altitude in the Atmosphere,based on the Ionization

As one gains altitude in the atmosphere,based on the ionization energies shown below,which sequence of mole fractions is the correct one?
Process Ionization Energy (kJ/mol)
N₂ + hν → N₂⁺ + e^- 1495
O₂ + hν → O₂⁺ + e^- 1205
O + hν → O⁺ + e^- 1313
NO + hν → NO⁺ + e^- 890

A) N₂ > N > NO > O₂
B) N₂ > O > O₂ > NO
C) N₂ > O₂ > O > NO
D) NO > O₂ > O > N₂
E) All will be equal.
