Answer: the correct option is D(the mass they are formed with).
Step-by-step explanation:
The formation of star occurs due to accumulation of gas and dust which collapses due to gravity and starts to form stars. The components of star includes:
- hydrogen( which is converted to helium in the cores of the star),
- carbon,
- nitrogen,
- oxygen and
- iron
All stars begin their lives with the same basic composition, but the characteristic that most determines how they will differ is
the mass they are formed with since most stars have small amounts of heavier elements( carbon, nitrogen, oxygen, iron) than others.
