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.
Pluto (if you still consider it as a planet),
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
Neptune, the furthest planet from the sun. Sometimes the dwarf planet Pluto comes inside its orbit.
Pluto (if you still consider it as a planet),
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.
