The Sun is almost entirely composed of:
OA. hydrogen and helium
Hydrogen and helium are the two main elements that make up the Sun. These elements are fused together through nuclear reactions in the Sun's core, releasing a tremendous amount of energy in the form of light and heat. This process, known as nuclear fusion, is what powers the Sun and allows it to shine brightly in our solar system.
So, the correct answer is Option A: hydrogen and helium.
