Answer:
A. The movement of the Earth along its orbit
Explanation:
The moon orbits the Earth once every 27.3 days. This is the sidereal month. It is measured against the background stars.
However, the Earth is also orbiting the Sun, and the moon needs extra time to catch up to its previous position relative to the Sun. This is the synodic month. It takes 29.5 days.
B is wrong. The rotational speed of the Earth constant. It makes one revolution every 23 h 56 min 4.09053 s.
C is wrong. The synchronous rotation of the moon does not affect its orbital speed.
D is wrong. The tilt of the Earth's axis affects only the moon's angle in the sky.
The environment is not hospitable to human life, and international treaties forbid any country from claiming territory in Antarctica, which a permanent residency would be doing by default. If you want cold and dark and very little interaction with other people, move to Finland.
Overwintering, in 100% darkness adds its own difficulties. Psychologically, it's very demanding. Living in close quarters with a small, unchanging group of people is very difficult, and the longer the stretch of time, the more of a strain it is on everyone. This is true even in much milder climates than Antarctica's.
