Which outcome results when stellar core hydrogen feedstock is locally depleted?

A)Increased core temperature and contraction
B)Decreased radiation pressure suspends fusion
C)Helium fusion prematurely begins uniformly
D)Suppressed CNO cycle causes core cooling

💡 Explanation

Increased core temperature and contraction occurs because depleted hydrogen fuel causes reduced outward radiation pressure; therefore gravitational collapse compresses and heats matter to ignite helium fusion, rather than the fusion stopping entirely under these extreme conditions.
