We can see stars because the following process produces light:
a. Helium and hydrogen atoms join together, which releases a large amount of energy
b. Helium nuclei divide to form hydrogen nuclei, which releases a large amount of energy
c. Hydrogen nuclei join to form helium nuclei, which releases a large amount of energy
d.Hydrogen and helium atoms on the surface of stars flare, which releases a large amount of energy
What is c. Hydrogen nuclei join to form helium nuclei, which releases a large amount of energy
