B and D are not true of Bohr's model of the atom. Bohr's model assumed that electron of a hydrogen atom travels in discrete elliptical orbits (not circular, as you have probably been taught) whose size depended on the allowed energy levels of the electron.

Answer:

D. electrons don't exist

Explanation:

Bohr's model describes an atom as a planet and predict that electrons orbit the nucleus of the atom at a quantised energy level referred to as shells. If not quantised, then the electrons ought to spiral into the nucleus due to the attractive Coulombic forces between the them. The shells are not planar as imagined.

The model do not predicts that electrons don't exist.
