Explica este código JavaScript

Dificultad: Intermedio

const one = () => {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      resolve("one")
    },5000)
  })
}

const two = () => {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      resolve("two")
    }, 2000)
  })
}

const three = () => {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      resolve("three")
    }, 0)
  })
}

const res = () => {
  return Promise.allSettled([one(), three(), two()])
}

res()
  .then(x => console.log(x))
  .catch(err => console.log(err))

A. (después de 5s)

[{
  status: "fulfilled",
  value: "one"
}, 
{
  status: "fulfilled",
  value: "three"
}, 
{
  status: "fulfilled",
  value: "two"
}
}]

B. (después de 2s)

[{
  status: "fulfilled",
  value: "one"
}, 
{
  status: "fulfilled",
  value: "three"
}, 
{
  status: "fulfilled",
  value: "two"
}
}]

C. (de manera inmediata, después de 0s)

[{
  status: "fulfilled",
  value: "three"
}]

D. Promise.allSettled() no existe en Javascript
