Why do stars give their own light?

Answer and explanation

Correct answer: Nuclear reactions occur inside them

Stars emit their own light because their extremely hot and dense interiors support nuclear fusion. In most ordinary stars, including the Sun, hydrogen nuclei combine to form helium. A small amount of mass is converted into a very large amount of energy, which eventually escapes as visible light, heat, and other radiation. This self-generated energy distinguishes a star from a planet or moon. Planets such as Earth and Mars do not normally produce starlike light; they mainly reflect light received from a star. Dust does not create light either. Therefore, option C correctly identifies the governing process.
