    Answer C.

    The electrons occupy energy levels/states. The Pauli exclusion principle does not allow all electrons in the same lowest state. Two electrons of opposite spin can occupy the lowest energy level, but the next two have to go to a higher level and so forth. After placing all electrons in the energy states, the state with the highest energy occupied has an energy level that we call the Fermi energy.
