supernova supergiant neutron star white dwarf
I gave my students this multiple choice question: The Sun is a medium-sized star and is expected to continue to perform nuclear fusion for five billion years. What is most likely to be the final stage of the Sun?

Only one answer is correct among these 4 choices:
- supernova
- supergiant
- neutron star
- white dwarf

Could you tell me which one is correct?

white dwarf
