Has Polaris always been the "North Star"?

Has Polaris always been the "North Star"?
A) No, because it is a young star that only formed a few hundred years ago.
B) No, because the Earth's axis slowly changes the direction it points.
C) No, because the Milky Way blocked our line of site to it for a long time.
D) Yes, because the stars are unchanging.
