A) The stars core shrinks
The star will contract under the weight of gravity.
When it contracts it will heat up and expand to a red giant.
When the star runs out completly of helium it would emit gasses and form a star nebula.
It would then become a white dwarf then into a black dwarf.

The star becomes a white dwarf when it begins to run out of fuel. Option C is correct.

Death of star:

It is a process of multiple steps by which a star loses its all energy and becomes a white dwarf.

This includes:

  • The core of the star starts to shrink. The star will contract due to the force of its own gravity.
  • Contraction heat up the star and the star starts to expand again.
  • But finally when most of the helium is used the star becomes a white dwarf.

Therefore, the star becomes a white dwarf when it begins to run out of fuel.
