Which characteristic changes when electron Degeneracy Pressure fails within stars?

A)Star's radius sharply decreases compressively
B)Fusion reactions suddenly become exothermic
C)Neutrino emission rates stabilize completely
D)Surface temperature shifts inconsistently

💡 Explanation

Degeneracy Pressure prevents collapse because Pauli Exclusion prevents compression into identical quantum states. Therefore the star's radius dramatically reduces when degeneracy pressure fails against gravity, rather than any change to nuclear fusion or neutrino flux under constant conditions.
