It is not massive enough.
Explanation: whether a star becomes a white dwarf, neutron star, or black hole depends on its mass. The Sun’s mass is far too low to undergo the core collapse needed to form a black hole. It will become a red giant, shed its outer layers as a planetary nebula, and leave behind a white dwarf (final core ≈0.5–0.7 solar masses). Only much more massive stars (initial masses ≳8–20+ solar masses, with black holes requiring the highest masses) can produce core collapses that leave neutron stars or black holes.
