The answer is C, have a good day!
Alpha particles have have 2 protons,<span> 2 </span>neutrons, ans 0 electron.
Answer:
The core turns its hydrogen to helium and stops nuclear fusion which causes the outer shells of hydrogen to collapse.
Explanation:
This results in higher temperature and pressure which in turn causes the outer shells to expand and cool as a red giant.
