- BRotation of the Earth on its own axis
- CRevolution of the Moon around the Sun
- DInteraction of the Earth with other planets

The seasons are caused by the 23.5-degree tilt of the Earth's axis: as the Earth revolves around the Sun, each hemisphere alternately tilts toward and away from the Sun, changing the angle and duration of solar insolation. Rotation on its axis causes day and night, while the Moon's revolution and the other planets play no role in the seasons. Hence option A.
