What is the primary component of the Sun?

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

Answer: (B)

The primary component of the Sun is hydrogen, which accounts for about 74% of its mass. Hydrogen atoms undergo nuclear fusion in the Sun's core, where extreme pressure and temperature enable these atoms to collide and fuse, creating helium along with a tremendous amount of energy in the form of light and heat. This process is what powers the Sun and emits the energy that sustains life on Earth. The significant presence of hydrogen makes it not only the most abundant element in the Sun but also a crucial factor in its fusion processes. Helium is generated as a byproduct of hydrogen fusion but is not the primary element. Other options such as oxygen and carbon dioxide represent much smaller percentages of the Sun’s composition and are not involved directly in the Sun’s fusion processes.
