Which of the following statements about degeneracy pressure is not true?
A)Explaining the origin of degeneracy pressure requires both the quantum mechanical exclusion principle and the uncertainty principle.
B)Degeneracy pressure stops the gravitational collapse of white dwarfs.
C)Degeneracy pressure stops the gravitational collapse of ordinary (main-sequence)stars like the Sun.
D)Degeneracy pressure halts the collapse of neutron stars.
E)Degeneracy pressure arises only with fermions (such as electrons,protons,and neutrons)and not with bosons (such as photons or helium nuclei).

Degeneracy pressure stops the gravitational collapse of white dwarfs and neutron stars, not ordinary (main-sequence) stars like the Sun. The Sun's gravitational collapse is balanced by the thermal pressure from nuclear fusion in its core, not by degeneracy pressure.
