What is the relationship between Bohr's model and the characteristic spectral lines of gases?
a. None. Bohr's model does not explain spectral lines.
b. The spectral lines are determined by the size of the initial orbit.

d. The spectral lines are determined by the absorption of photons by the atom.
e. The spectral lines are determined by the angles at which electrons are emitted when light hits them.
