The apparent motion of the sun across the sky during the day is primarily caused by **Earth's rotation**. As the Earth rotates on its axis from west to east, the sun appears to move across the sky from east to west. This rotation gives the illusion that the sun is moving, while in reality, it is the Earth that is turning.
The other options you mentioned are not correct in explaining the daily motion of the sun:
- The movement of stars is also due to the Earth's rotation, but it doesn't cause the sun's apparent motion specifically.
- The moon's orbit does not influence the sun's apparent motion.
- The sun does not move around the Earth; rather, the Earth orbits the sun.
So the correct answer is **Earth's rotation**.
