The stages that all stars have in common in their life cycles are:
1. **Nebula**: This is the initial stage where stars form from clouds of gas and dust.
2. **Protostar**: After the nebula, the material condenses into a protostar as gravitational forces pull the material together.
3. **Main Sequence**: While not listed in your options, this is a crucial stage where stars spend most of their lives fusing hydrogen into helium in their cores.
4. **Red Giant (or Supergiant)**: This stage follows the main sequence for stars larger than the Sun or smaller.
5. **Final Stages**: Depending on the mass of the star, it may end as a white dwarf, neutron star, or black hole.
From the options you provided, the common stages would be **nebula** and **protostar**.
If you specifically need to choose only one, **protostar** is often highlighted as a definitive stage in stellar formation after the initial nebula phase. However, both **nebula** and **protostar** are essential starting points in the life cycle of all stars.
