Correct answer: C. The sun will then expand into a red giant and possibly swallow the inner planets, including Earth
- A. The sun will then expand into a red giant and possibly swallow the outer planets
- B. The sun will then expand into a red giant and possibly swallow the inner as well as outer planets, including Earth
- C. The sun will then expand into a red giant and possibly swallow the inner planets, including Earth
- D. Sun will stay as it is
