The Interiors of White Dwarf Stars Are Characteristically

The interiors of white dwarf stars are characteristically

A) mainly carbon and oxygen nuclei supported by electron degeneracy pressure in a volume about the size of the Sun.
B) mostly hydrogen nuclei supported by normal gas pressure due to the very high gas temperature, in a volume about the size of Earth.
C) mainly carbon and oxygen nuclei supported by electron degeneracy pressure in a volume about the size of Earth.
D) mainly helium nuclei supported by electron degeneracy pressure in a volume with a radius about 11 times that of Earth, about the volume of Jupiter.
