Energy within the sun is produced through (a)  

• Nuclear fusion

• Nuclear fission

Answer explanation

Energy within the sun is produced through nuclear fusion, where hydrogen nuclei combine to form helium, releasing vast amounts of energy. Nuclear fission, on the other hand, involves splitting heavy nuclei and does not occur in the sun.
