The correct statement is:
**They have valence electrons in the same energy level.**
Both nitrogen and oxygen are in the second period of the periodic table, meaning they have their valence electrons in the second energy level. Nitrogen has five valence electrons (2s² 2p³) and oxygen has six valence electrons (2s² 2p⁴). Although the number of valence electrons differs, they are both in the same energy level.
