Pluto's largest moon is?

Explanation:
Charon is Pluto’s largest moon because its size is the greatest among the moons that orbit Pluto. Its diameter is about 1,200 kilometers, which is much larger than the other known Pluto moons, which are only tens of kilometers across. Because of this, Charon also contributes a substantial portion of the Pluto–Charon system’s mass, leading to a barycenter that lies outside Pluto itself. This combination—being the biggest by size and mass—makes Charon the largest moon around Pluto, bigger than Nix, Hydra, or Kerberos.
