A student tries to use Bohr's formula to predict the spectrum of a neutral helium atom, which has two electrons, and the predictions disagree with experiment. Read the Assertion (A) and Reason (R) and choose the correct option.

Assertion (A): The Bohr model cannot give accurate energy levels for a neutral helium atom.
Reason (R): The Bohr model considers only the attraction between one electron and the nucleus and ignores the repulsion between electrons.
