Which of the following best describes the Kuiper Belt?

The Kuiper Belt is best described as a region populated with dwarf planets and icy bodies beyond Neptune. This area is located in the outer solar system and is primarily composed of small celestial objects made largely of ice and rock. It is situated approximately 30 to 55 astronomical units (AU) from the Sun and is known for containing a variety of objects, including dwarf planets such as Pluto, Haumea, and Makemake, as well as many other smaller icy bodies.

The Kuiper Belt is significant for several reasons: it helps astronomers understand the early solar system, contributes to our knowledge of planetary formation, and serves as a source of comets. When comparing this to the other options, the Kuiper Belt is distinct and specifically characterized by its composition and location beyond Neptune, making option C the most accurate description.
