A) because helium is very explosive and cannot be controlled when the nuclear reactions occur.
B) because degenerate electrons in the core do not allow the core to expand as it heats up.
C) in Cepheid variables.

E) none of the above

Question

Quizplus · Accepted Answer

Helium flash occurs in stars with degenerate electron cores, where the core cannot expand to cool down as it heats up, leading to a rapid onset of helium fusion.
