According to the Bohr model of the atom, energy is emitted as light when electrons O fall back down to a lower energy level
O jump up to a higher energy level
are absorbed into the nucleus
O are ejected from the nucleus

After jumping to the higher energy level also called the excited state the excited electron would be in a less stable position, so it would quickly emit a photon to relax back to a lower, more stable energy level.

the answer would be b i believe
