Which of the following statements about fusion is correct?
it is not a naturally occurring process.
it is currently used as a source of commercial energy production on earth.
it can create heavier elements, like oxygen and nitrogen, from hydrogen and helium.
it is similar to radioactive decay in that it occurs on its own without stimulation.

The first point is correct

Explanation:

Unlike fission, which is similar to radioactive decay, fusion does not occur naturally and this is due to the strong repulsive electrostatic forces which pull the positively charged nuclei apart from coming together and collide for fusion to occur.
