C) nuclear fusion.
D) stellar nucleosynthesis.

Question

Quizplus · Accepted Answer

The process of forming the earliest isotopes of low-mass nuclei such as deuterium, helium, lithium, beryllium, and boron is known as Big Bang nucleosynthesis. It occurred during the first few minutes of the universe's existence when the temperature and density were high enough for nuclear reactions to occur. These elements were created through a series of fusion reactions, starting with hydrogen and helium nuclei combining to form deuterium, which then combined with more hydrogen to form helium-3 and eventually helium-4.
