Which of the following accurately describes the main reaction that generates the Sun's light?

Question

Oxygen reacts with carbon to form carbon dioxide.
Iron reacts with oxygen to form iron oxide.
Hydrogen nuclei fuse, forming helium and releasing energy.
Light reacts with water to form glucose.

Answer 1

The statement that accurately describes the main reaction that generates the Sun's light is:

Hydrogen nuclei fuse, forming helium and releasing energy.

This process is known as nuclear fusion, and it occurs in the Sun's core, where hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the form of light and heat.
