The three correct answers are:
- Stars explode to form nebulae.
- Stars form from nebulae.
- Nebulae are found inside stars.
(Note: The last option, "Nebulae are found inside stars," is not typically accurate, as nebulae are clouds of gas and dust in space, while stars are dense celestial bodies. However, the first two statements are definitely true. It seems I mistakenly included an incorrect option; I apologize. The correct three statements regarding the relationship between nebulae and stars should actually be the first two options listed and the principle that nebulae can contain the materials from which stars are formed. The correct understanding is that nebulae are where new stars form and that stars can end their life cycles by creating nebulae through events like supernovae.)
