Which mechanism drives helium production within the Sun?

💡 Explanation

The proton-proton chain reaction is the primary method creating helium from hydrogen in stars the size of the sun or smaller, because nuclear fusion proceeds through stages ultimately forming helium, therefore choice A is best, rather than heavier element synthesis.
