Which critical mechanism triggers helium flash within degenerate matter?

A)Triple-alpha process runaway
B)CNO cycle instability
C)Proton-proton chain collapse
D)Rapid neutron capture ignition

💡 Explanation

The triple-alpha process ignites unstably because electron degeneracy prevents expansion. Increased temperature accelerates fusion via the triple-alpha process, therefore a runaway reaction occurs, rather than a controlled burn due to lacking pressure-temperature feedback.
