Answer: Option (b) is the correct answer.
Step-by-step explanation:
According to Rutherford, nucleus of an atom is located at the center and electrons revolve around the nucleus of the atom.
Whereas a nucleus contains protons and neutrons together.
Whereas Bohr stated that electrons revolve around the nucleus in energy levels. Further, he stated that electrons not just occupy any energy level.
Thus, we can conclude that Bohr's model of the atom include that Rutherford's model did not have energy levels.
