Answer 2

Nuclear fusion.

Step-by-step explanation:

Nuclear fusion is the process in which atomic nuclei colide to form a new nucleus with higher atomic mass.

The fusion process reduces the total mass of the particles involved, wich means that energy will be produced, according to the mass-energy equivalence equation: E = mc².

This energy will promote electronic transitions that will lead to visible light emission.
