Identify the fact A. Revolution of the Earth

B. Tilt of the earth's axis

C. Parallelism of the Earth's axis

D. Rotation of the Earth

Option (d) is correct because rotation of the Earth is not responsible for the occurrence of seasons. It is responsible for daylight and night time.

Option (a) is not correct because revolution of the Earth is responsible for the occurrence of seasons. It not only affects but causes the temperature conditions that give us spring, summer, fall and winter seasons.

Option (b) is not correct because tilt of the Earth’s axis is responsible for the occurrence of seasons. Earth is a sphere tilted on its axis. As the Earth goes around the sun, the part that is closer to sun gets more sunlight and experience summer where as the part away from the sun experience winter.

Option (c) is not correct because parallelism of the Earth’s axis is responsible for the occurrence of seasons. Parallelism accounts for the intensity and duration of solar radiation an area of Earth receives and therefore the intensity and duration of seasons.
