15) most of the radiant energy released by the sun results from the process of\na) electrical generation\nb) nuclear fission\nc) nuclear fusion\nd) combustion
Answer
Brief Explanations:
The sun generates energy mainly through nuclear fusion in its core, where hydrogen atoms combine to form helium, releasing a vast amount of energy in the process. Electrical generation is not the source of the sun's energy. Nuclear fission is the splitting of atoms and is not the main process in the sun. Combustion requires oxygen and is not applicable to the sun's energy - producing mechanism.
Answer:
C. nuclear fusion
