Stellar evolution is the life cycle of a star. A cycle suggests that upon death of a star, another star is born. How is this possible? A. Stars never really die. B. The death is a black dwarf star. This type of death triggers the birth of a new star. C. The death is a red giant. This type of death emits red energy that forms a new star. D. The death is a supernova. This type of death can produce nebular clouds and trigger the birth of a new star.

star never really die

Explanation:

Because stars dont die

Option - B

The death is a black dwarf star. This type of death triggers the birth of a new star. Stars are comprised of a number of mixture of gases as we know that due to the losses that happens inside the celestial objects the energy inside which they posses runs out of stock or it decrease and it then form the red dwarf which is the magnanimous form of mixture of gases. On further contraction of this mass which is really due to the extensive amount of gravity been placed inside them, there is a formation of nebula or we can say more different celestial entity. And at the end if the star is not big enough or too large as compared to our sun, then it would turn into a black dwarf, or in other cases if the star which forms the nebula is too large then it will be then transformed into a black hole depending upon the size of the star.
