The correct answer is: All of the above.
The correct answer is all of the above.
A star is a ball of burning plasma, mainly composed of hydrogen and helium. It is formed through the process of clouds of gas in space colliding, which then triggers nuclear fusion. Nuclear fusion is the process through which most elements are formed and released into the universe. Therefore, all three statements are true and accurately describe what a star is.
