What Happens When a Core's Mass Is Less Than 3

What happens when a core's mass is less than 3 solar masses but greater than 1.44 solar masses

A) Electron degeneracy pressure can no longer support the core and the electrons combine with the protons to generate neutrons and neutrinos, the neutrinos of which supply neutron degeneracy pressure to support the neutron star.
B) Electron degeneracy pressure can no longer support the core and the electrons combine with the protons to generate neutrons and neutrinos, the neutrons of which supply neutron degeneracy pressure to support the neutron star.
C) Electron degeneracy pressure supports the core of the white dwarf.
D) Electron degeneracy pressure can no longer support the core and the electrons combine with the protons to generate neutrons and neutrinos, the neutrinos of which supply neutron degeneracy pressure to support the black hole star.
