Answer 1

The correct response is:

It is not massive enough.

Astronomers believe that only stars with a sufficient mass, typically at least about 20 times the mass of the Sun, can end their life cycles as black holes. The Sun, being a medium-sized star, will instead end its life cycle as a white dwarf after going through the red giant phase.
