What stages would a low mass star pass through in its lifetime

Low mass star phases

Explanation:

Helium fuses into carbon, the core of the star collapses. Once this happens, the outer layers become exhausted from the weight and this leads a planetary nebula to be formed from the outer layers. The core of the star remains a white dwarf for some time, but eventually it cools down and evolves to a black dwarf.

the correct answer would be d. hope this !

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
