Answer:

The correct answer is n = 1

Explanation:

The moment the photon is emitted, the electron transaction occurs from a higher main energy level to a lower main energy level. Considering that the only main energy level below n = 2 is n = 1, so this is the energy level the electron must transition when the photon is emitted.
