What is the primary component of the Sun's composition?

• A. Helium
• B. Oxygen
• C. Hydrogen
• D. Carbon

Answer: (C)

The primary component of the Sun's composition is hydrogen. Approximately 74% of the Sun's mass is made up of hydrogen. It serves as the primary fuel for the nuclear fusion reactions that occur in the Sun's core, where hydrogen nuclei combine to form helium, releasing vast amounts of energy in the process. This energy is what powers the Sun and provides light and heat to our solar system. Helium, while the second most abundant element in the Sun, makes up only about 24% of its mass. The other elements, such as oxygen and carbon, are present in much smaller quantities, usually less than 2%. These trace elements contribute to various processes and reactions in the Sun, but hydrogen remains the dominant element, playing a crucial role in the Sun's life cycle and energy production.
