Explanation:

When an electron falls from a higher - energy level to a lower - energy level within an atom, it loses energy. This energy is released in the form of a photon. An electron cannot move from a lower to a higher level spontaneously in this context. Absorbing a photon is what causes an electron to move to a higher level. And there is no swapping of electrons as described in the option.

Answer:

A photon is given off.
