All of the above
All of the above is correct. A star is a ball of burning plasma, mostly made up of hydrogen and helium. It is formed as a result of clouds of gas in space colliding and causing nuclear fusion. This process also leads to the formation and release of most elements into the universe.

The life cycle of a star depends primarily on its mass. The mass of a star determines its luminosity, apparent magnitude, and age. These factors all play a role in determining the various stages a star goes through during its life cycle, including its formation, main sequence phase, red giant phase, and possible supernova or white dwarf stage.
