Explanation:

1.

The apparent rotation of the sky is due to the Earth's rotation on its axis. As the Earth rotates from west - to - east, stars appear to move from east to west across the sky for an observer on Earth.

The key factor in determining whether a star is circumpolar (never sets), a rise - and - set star, or a never - rise star is the observer's latitude. At higher latitudes, more stars are circumpolar.

Circumpolar stars are those that remain above the horizon at all times for a particular observer. Their status (circumpolar, rise - set, never - rise) depends on the observer's location on Earth, specifically latitude.

Answer:

B. From east to west
