Answer

In Bohr's model, the 'quantization of energy' means that electrons can only exist in specific, discrete energy levels or orbits around the nucleus. They cannot occupy energy levels in between these allowed orbits. Electrons can move from one energy level to another by absorbing or emitting a specific quantum of energy (a photon) corresponding to the energy difference between the levels.
