Answer:

Nuclear fusion is a correct option

Explanation:

Nuclear fusion processes begin when the star enters the main sequence.

Nuclear fusion: by which energy is produced by the star,the star become the main sequence star and it gets turned on.

Formation of a star takes place when it is very hot, hydrogen atom fuse to form helium in the core region,and energy is released by the fusion process and star enters the main sequence by the processes nuclear fusion.

This fusion results in outward pressure which balances the inward pressure, which is caused by gravity and thus stabilizes the star.

Thus Nuclear fusion processes begins when a star enters the main sequence.
