The correct response is:
It shows electron orbitals as regions of space.
The Schrödinger model (quantum mechanical model) of the atom describes electrons as existing in probabilistic orbitals around the nucleus, rather than fixed orbits as in the Bohr model. The Bohr model describes electrons in defined circular orbits with specific energy levels, while the Schrödinger model provides a more complex view of electron behavior in terms of probabilities and wavefunctions.
