According to Neils Bohr, an electron in an excited state could give off

B) at most a single photon until the atom was excited again.
C) a continuous cascade of photons for a high-level transition.
D) none of these

Bohr's model suggests that an electron can transition between different energy levels within an atom. When moving from a higher to a lower energy level, it emits a photon for each transition. Therefore, an electron in an excited state can indeed emit several photons as it moves through intermediate levels back to the ground state.
