f

Answer 1

True

Step-by-step explanation:

The proton-proton chain is a nuclear fusion reaction that occurs in the core of the sun, where four hydrogen nuclei (protons) are fused together to form one helium nucleus. This process releases a large amount of energy in the form of light and heat, which is what powers the sun and sustains life on Earth.
