← ScienceWhich consequence results when critical binding energy decreases in stellar nucleosynthesis?
A)Increased neutron decay rates develop
B)Iron production terminates stellar fusion✓
C)Protium converts entirely to helium
D)Beta decay strengthens plasma confinement
💡 Explanation
Iron's high binding energy makes it the endpoint; therefore, fusion stops, rather than continuing to heavier elements, because the energy investment exceeds energy output beyond iron via nuclear binding energy.
