How does a black hole form from a massive star?
A)A black hole forms when two massive main- sequence stars collide.
B)If enough mass is accreted by a white dwarf star that it exceeds the 1.4 solar mass limit, it will undergo a supernova explosion and leave behind a black- hole remnant.
C)If enough mass is accreted by a neutron star, it will undergo a supernova explosion and leave behind a black- hole remnant.
D)Any star that is more massive than 8 solar masses will undergo a supernova explosion and leave behind a black hole remnant.
E)During a supernova, if a star is massive enough for its gravity to overcome neutron degeneracy pressure in the core, the core will collapse to a black hole.

During a supernova, if a star is massive enough for its gravity to overcome neutron degeneracy pressure in the core, the core will collapse to a black hole. This occurs when a star has a mass of more than about 20 times that of the Sun. As the core collapses, it becomes incredibly dense and compact, with gravity so strong that not even light can escape. This is how a black hole is formed from a massive star.
