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 reflects the process: first, the star exhausts its nuclear fuel, leading to a loss of outward pressure from fusion. Then, gravity takes over, causing the star to collapse. This often triggers a supernova explosion, after which the core that remains can collapse into a black hole if it is sufficiently massive.
