Question

Quizplus · Accepted Answer

Stars that eject a planetary nebula are typically low- to intermediate-mass stars that have reached the end of their lives. They go through a phase of being a red giant, during which they expand and shed their outer layers, creating a planetary nebula. Eventually, the core of the star will collapse and become a white dwarf, which is the remnant of the star after it has exhausted its nuclear fuel. Therefore, the best choice is C, white dwarfs, as they are the end product of stars that have ejected a planetary nebula.
