Question
the life and death of stars
the life and death of stars: white dwarfs, supernova
multiple - choice question
for our purposes we are going to simplify this. select the correct option below.
deuterons yield helium
h + h -> hydrogen
h + h -> he
he -> h + h
The image shows deuterons (isotopes of hydrogen) fusing to form helium. In nuclear fusion in stars, hydrogen - hydrogen fusion results in helium formation. The correct nuclear reaction is when two hydrogen nuclei (H + H) combine to form helium (He).

None of the provided options are correct as written. The correct reaction for hydrogen - hydrogen fusion to form helium is typically written as \(4H
ightarrow He + 2e^{+}+2
u_{e}\) (a more complete form including positrons and neutrinos). But among the given options, the closest conceptually correct one would be if the intention was \(H + H
ightarrow He\) (although the given options have incorrect notations). If we assume a very simplified view and correct the notations, the correct one would be a reaction where two hydrogens combine to form helium.
