Question

question 3
at the center of stars like the sun, fusion turns hydrogen into
plasma via helioseismology
radiation & elements like carbon & nitrogen
helium, energy, & neutrinos
sunspots

Explanation:

In the core of stars like the Sun, hydrogen - hydrogen fusion reactions occur. These reactions convert hydrogen into helium, release energy in the form of photons, and also produce neutrinos. Helium is the main product of hydrogen fusion in stellar cores.
