Explanation:

At the north pole (and south pole), due to the Earth's rotation axis, stars appear to circle around the zenith (the point directly overhead) and do not rise and set in the traditional sense. At the equator, stars rise and set perpendicular to the horizon, and at other latitudes like that of Washington D.C., the star - rising and setting patterns are more complex.

Answer:

D. At the north pole
