Answer Details

Bohr’s atomic model is most successful for explaining the structure of the hydrogen atom and the line spectra of the hydrogen atom. Therefore, statements I and II are correct. However, the model is not as successful in explaining multi-electron atoms, so statement III is incorrect. The correct answer is (c) I and II only.
