Which statement describes the formation of a nebula?

Question

An elliptical flattened disk begins.
A bulging core with irregular stars around it forms.
A large flattened core at the center contracts.
Gases from a dead star gather and contract.

Answer 1

The statement that best describes the formation of a nebula is: Gases from a dead star gather and contract.

This describes the process in which the remnants of stars, including gas and dust, can accumulate and eventually lead to the formation of a nebula. Nebulae are often formed from the ejected material of stars at the end of their life cycles, such as supernova explosions.
