Which outcome results when stellar iron fusion ceases within a supergiant star?

A)Core collapse accelerates rapidly
B)Helium flash ignites prematurely
C)CNO cycle reactions intensify slightly
D)Star's outer layers stably contract

💡 Explanation

Core collapse accelerates because iron fusion consumes, rather than releases, energy; therefore, the radiation pressure from fusion declines significantly, triggering gravity to overwhelm electron degeneracy pressure, leading to rapid implosion rather than stability or other fusion processes.
