Which mechanism causes electron degeneracy pressure to prevent gravitational collapse in white dwarf stars?

A)Pauli exclusion restricting electron configuration✓

B)Uncertainty principle broadening electron momentum

C)Coulomb repulsion offsetting gravity directly

D)Relativistic effects increasing particle mass

💡 Explanation

When stars collapse, electrons are forced into smaller volumes, and Pauli exclusion prevents them from occupying the same quantum state, generating degeneracy pressure opposing gravity. Therefore exclusion principle results, rather than uncertainty, Coulomb repulsion or relativistic mass increase, which are negligible compared to degeneracy pressure at these densities.
