A Stellar Core of About 2 Solar Masses Collapses Inward

Multiple Choice

A stellar core of about 2 solar masses collapses inward in a supernova explosion. What is the result of this collapse?

A) neutron star supported from further collapse by neutron-degeneracy pressure
B) black hole with infinitely small radius because nothing can prevent such a mass from collapsing completely
C) star a little smaller than the size of the Sun supported from further collapse by gas pressure from the hot interior of the star
D) white dwarf star supported from further collapse by degenerate-electron pressure
