Correct option is C
The Sun generates energy through the process of nuclear fusion. In the core of the Sun, hydrogen nuclei fuse together to form helium, releasing vast amounts of energy in the process. This fusion process involves high temperature and pressure, allowing protons to overcome their repulsion and combine. The energy released in the form of heat and light sustains life on Earth and powers the solar system.
Nuclear fusion is different from nuclear fission, where heavy nuclei split into smaller ones, releasing energy. Fusion is the source of energy in stars, including the Sun.
