Final answer:
All types of dwarfs, including white dwarfs, red dwarfs, and brown dwarfs, have similar sizes.
Step-by-step explanation:
Out of the given options, All are about the same size is the correct answer.
Brown dwarfs are known to have a radius similar to that of Jupiter, regardless of their masses. Even though they have different masses ranging from about 13 to 80 times the mass of Jupiter, their sizes remain the same. This means that all types of dwarfs, including white dwarfs, red dwarfs, and brown dwarfs, have comparable sizes.
