The sun is a star. The sar is a
ball of hot gases containing different kinds of elements at different cores. It
has a very high temperature that radiates all throughout the Milky Way galaxy.
The sun has four main parts; the core, photosphere, chromospheres and corona.
The outer core of a star located at the chromospheres contains mostly of

silicon and the inert gas. When a star releases energy it is due to the
thermonuclear fusion of hydrogen into helium. So the answer is letter C.
