Which of the following correctly compares the Sun's energy generation process to the energy generation process in human-built nuclear power plants?
A) The Sun generates energy by fusing small nuclei into larger ones, while our power plants generate energy by the fission (splitting) of large nuclei. B) Both processes involve nuclear fusion, but the Sun fuses hydrogen while nuclear power plants fuse uranium. C) The Sun generates energy through nuclear reactions while nuclear power plants generate energy through chemical reactions. D) The Sun generates energy through fission while nuclear power plants generate energy through fusion.
