Which of the following is true of the central star of a planetary nebula?

Question

Quizplus · Accepted Answer

The central star of a planetary nebula is formed when a low or intermediate mass star has exhausted all its nuclear fuel and shed its outer layers. The remaining hot core will then ionize the surrounding gas to form a planetary nebula. The core will eventually cool down to become a white dwarf, so option A is the correct answer. Option B is incorrect, as the central star is not massive enough to produce a supernova. Option C is incorrect because a main sequence star is still undergoing nuclear fusion, and option D is incorrect because a proto-star has not yet reached the point of nuclear fusion.
