The correct answer is: C
A. This is incorrect because the text doesn't mention the width or size of the Kuiper Belt. It mentions that a Kuiper Belt Object (KPO) is larger than 20 miles across, but it doesn't refer to the entire belt being 20 miles across.
B. This is incorrect because the text doesn't associate the Kuiper Belt with Neptune's rings. The Kuiper Belt is a region of the solar system beyond the orbit of Neptune, but it's not one of Neptune's rings.
C. This is correct. The text describes the Kuiper Belt as an area with many small objects that orbit the sun. It is a region in the outer solar system beyond Neptune's orbit that contains various small, icy bodies, including Pluto.
D. This is incorrect because the text states that Pluto takes 248 years to orbit the Sun, but it doesn't mention anything about Pluto having five moons that take over 248 years to orbit the Sun.
Therefore, option C accurately describes the Kuiper Belt based on the information provided in the text.
