Which consequence results when iron-56 concentration rises in a star's core?

💡 Explanation

Gravitational collapse increases because iron-56 has the highest nuclear binding energy per nucleon; therefore, fusion ceases and outward radiation pressure drops, reducing support against gravity, rather than initiating further fusion which would maintain stability.
