B. Pluto is smaller than all of the eight planets.

C. Pluto has a moon, Charon, which is more than half its size and larger than other planets’ moons.

D. Since it's not large enough to clear its orbital path, it's not considered a planet.

The answer is D since in order to be recognized as a planet it needs to follow these three criteria
-A planet must be round.
-A planet must orbit the sun.
-A planet must have “cleared the neighborhood" of its orbit. This means that as a planet travels, its gravity sweeps and clears the space around it of other objects. Some of the objects may crash into the planet, others may become moons.
