The best description that summarizes the steps that take place during black hole formation, in the correct order, is:
A massive star depletes its nuclear fuel; gravity overpowers the star; supernova occurs; core of star collapses.
This sequence accurately represents the process of black hole formation: a massive star uses up its nuclear fuel, leading to gravitational collapse, followed by a supernova explosion, resulting in the core collapsing further to potentially form a black hole.
