A.
It is too far from the Sun.
B.
Its orbit is not cleared of like-sized or larger objects.
C.
It is not large enough in size.
D.
It does not have rings.
the answer is C
Pluto has three known moons, the largest is called Charon.
A dwarf planet is a celestial body that orbits the Sun and has enough mass to be nearly spherical, but has not cleared its orbit of other debris. Pluto is a notable example of a dwarf planet in our solar system.
The terms "outer planet" and "inner planet" are only used for planets. Pluto is not a planet, and it orbits beyond the outer planets.
Neptune, the furthest planet from the sun. Sometimes the dwarf planet Pluto comes inside its orbit.
Back when Pluto was a planet and not a dwarf planet, it sometimes Neptune to be the ninth planet because their orbit crossed. Now that Pluto is a dwarf planet, there are only eight planets in the solar system.
Planetry orbits are elliptical. Most planet's orbits are nearly circular apart from Mercury and Pluto.
Pluto has three known moons, the largest is called Charon.
Pluto has a tilted orbit (compared with the average plane of the orbits of the other planets). Also, Pluto would be considered a "terrestrial planet", but it is not now defined as a planet. It's just called a "dwarf planet" now.
Pluto, which is a planetesimal, not a planet, orbits the star called Sol. Sol gives its name to our Sol-ar system, and is often called, "The Sun."
Pluto is a dwarf planet and trans-neptunian object. Crossing orbits with Neptune stops Pluto being a planet.
Pluto isn't a moon, it orbits the sun, but it is a dwarf planet

It is a moon of the dwarf planet Pluto. They are so nearly the same size it could almost be called a double planet system

Pluto is a dwarf planet that orbits the Sun. It is not known to be a piece of something else.
