Answer:
Fusion
Explanation:
Because fusion is when two light nuclei combine together releasing high energy(light and heat in our case)
Answer:
A) fusion
Explanation:
The process by which a star like our Sun produces its energy is nuclear fusion, which consists of the union of nuclei of certain elements to form other elements.
Since the sun, like the other stars, are very massive objects, they have a very intense gravitational field, which causes the star to compress, which causes its nucleus to reach very high temperatures and then nuclear fusion occurs.
Fusion realeses a lot of energy, and this energy is what makes the sun shine, and also help it to not collapse under its own gravity
