The Bohr model of the atom explained why emission spectra are discrete. It could also be used to explain the photoelectric effect. Which is a correct explanation of the photoelectric effect according to the model?

In the Bohr model, electrons occupy discrete energy levels, so they can absorb only specific amounts of energy to move to another level. An electron is emitted only if it absorbs enough energy to overcome its binding energy; this requires a threshold amount of energy. Thus, electrons need specific amounts of energy to jump levels and be emitted.
