The correct answer is: C. The earth rotates from east to west.
The Earth rotates on its axis once every 24 hours. This rotation causes the Sun, Moon, and stars to appear to move across the sky from east to west.
Option A is incorrect because not all stars move from east to west. The Earth’s rotation causes the stars to appear to move across the sky from east to west, but the stars themselves are not actually moving.
Option B is incorrect because the Earth does not rotate from west to east. The Earth rotates from east to west.
Option D is incorrect because the background of the stars does not move. The stars themselves are moving, but the background of the stars is not.
