Answer:

D. Quantum mechanical model

Explanation:

Erwin Schrödinger proposed the quantum mechanical model of the atom, which treats electrons as matter waves. ... Electrons have an intrinsic property called spin, and an electron can have one of two possible spin values: spin-up or spin-down. Any two electrons occupying the same orbital must have opposite spins.
