Which stages do all stars have in common in their life cycles?(1 point)

All stars have certain stages in common in their life cycles. The primary stages include:

1. **Nebula** - The star begins its life in a nebula, a cloud of gas and dust.
2. **Protostar** - As gravity pulls the materials together, they form a protostar.
3. **Main Sequence** - This is a stable period where the star fuses hydrogen into helium.

After these stages, stars can evolve into different paths that may include becoming a red giant, supernova, and ending as a white dwarf, neutron star, or black hole, depending on their mass.

Given the options you've provided, the stages that all stars have in common in their life cycles are:

- **Nebula**
- **Protostar**

The other options (white dwarf and black hole) apply only to specific types of stars based on their mass and evolutionary path.
