Quizplus · Accepted Answer

The fact that Pluto is regarded by many to be a planet does not necessarily support the idea that it is a Kuiper-belt object. In fact, it was originally classified as a planet before being reclassified as a dwarf planet, which is also a type of Kuiper-belt object. The other options all provide support for the idea that Pluto is a Kuiper-belt object, including its cometlike composition and density (A), the presence of moons around asteroids (C), its more eccentric orbit than other planets (D), and the existence of other Kuiper-belt objects that are large (E).
