Final answer:

False. White dwarfs are the remnants of low- to medium-mass stars after they exhaust their nuclear fuel. The formation of a white dwarf is often accompanied by the production of a planetary nebula.

Step-by-step explanation:

False

White dwarfs are the remnants of low- to medium-mass stars (up to about 8 solar masses) after they exhaust their nuclear fuel. These stars go through the process of shedding their outer layers and losing a significant fraction of their mass. The remaining core of the star collapses under its own gravity and contracts to form a white dwarf. The formation of a white dwarf is often accompanied by the production of a planetary nebula, which is a shell of gas and dust ejected from the star.
