What are the possible remnants of supernovae?

protostars or nebulae

neutron stars or black holes

white dwarfs or protostars

black dwarfs or white dwarfs

Supernovae occur during the last stellar evolutionary stages of a star's life, either a massive star or a white dwarf, whose destruction is marked by one final, titanic explosion. Supernovae may expel much, if not all, of the material away from a star. However, if the explosion is weak enough, the star may collapse into a black hole or neutron star with little radiated energy.
