Based on the information in the graph, why is energy released during the fusion of hydrogen (h) into helium (He)?
A. The helium (He) nucleus is more stable than the hydrogen (H) nuclei are, because more mass is converted into binding energy in helium.
B. There are fewer nucleons in a helium-4 (He-4) nucleus that there are in four hydrogen-1 (H-1) nuclei, so there is more energy released per nucleon when helium forms.
C. The hydrogen-1 nuclei (H-1) are more stable than the helium-4 (He-4) nucleus is, because they have less binding energy per nucleon than the helium has.
D. The hydrogen (H) nuclei are lower in energy than the helium (He) nucleus is, so more energy is stored in a helium nucleus.
