Answer 1

The correct response is:

It is not massive enough.

Astronomers believe that the sun will not end its life cycle as a black hole because it does not have sufficient mass. Only stars with a mass greater than about 20 times that of the sun are thought to end their lives as black holes after undergoing supernova explosions. The sun is expected to evolve into a red giant and eventually shed its outer layers to form a planetary nebula, leaving behind a white dwarf.
