Which process terminates fusion within main-sequence stars nearing exhaustion?

💡 Explanation

Gravitational collapse ends fusion as the core's temperature increases via gravitational potential energy release rather than fusion because core material ceases to burn. Therefore, collapse occurs rather than equilibrium because radiation pressure decreases.
