The three correct answers that describe the relationship between nebulae and stars are:
- Stars form from nebulae.
- Stars explode to form nebulae.
- Nebulae form from stars.
These statements capture the cycle of star formation and the role of nebulae in that process. Stars form from the gas and dust in nebulae, and when stars reach the end of their life cycles, they can explode (in events like supernovae), contributing to the material that makes up new nebulae. Additionally, nebulae can also form from the remnants of stars.
