Helium-4  is most likely to be produced during a nuclear fusion reaction in the Sun

Helium-4

Explanation:

Nuclear fusion is the reaction in which the nuclei combines to form a bigger nuclei. The process of nuclear fusion occur naturally inside the sun because the temperature and density inside the sun is optimum for the reaction to take place.

In the process of nuclear fusion, nuclei of four hydrogen atom fuse to form a helium atom and two positrons. This is an exothermic reaction in which energy is released. The energy produced during nuclear fusion is relatively greater than the nuclear fission.
