The sun (or any star)
A
Nuclear Fusion
B
Nuclear Fission
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.

Detailed explanation-2: -In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion.

Detailed explanation-3: -The light and heat from stars is made by a process called nuclear fusion. Fusion happens when 2 atoms are forced together to form a heavier atom. This creates a lot of energy. However, fusion can only occur at the incredibly high temperatures and pressures found in the centre of stars.

Detailed explanation-4: -Nuclear Fusion in Stars Depending upon the age and mass of a star, the energy may come from proton-proton fusion, helium fusion, or the carbon cycle.

Detailed explanation-5: -Scientists at the National Ignition Facility (NIF), Lawrence Livermore National Laboratory (LLNL), in the United States recently reported they had generated more energy from a fusion test than the experiment had used (3.15 megajoules versus 2.05 MJ), or what is known as “net energy gain” from fusion.
