What statement describes the process of solar nuclear fusion? hydrogen atoms are fused into deuterium, then helium-3, then helium-4, each step giving off large amounts of energy. hydrogen molecules are fused together and become oxygen molecules, giving off large amounts of energy. helium molecules are fused together and become hydrogen molecules, giving off large amounts of energy. hydrogen atoms are fused into deuterium, then helium-4, then back into hydrogen, each step giving off large amounts of energy.
