    • C.

      The sun's temperature

    • D.

      The calendar

    Correct Answer
    B. The angle of Earth's axis
    Explanation
    The correct answer is the angle of Earth's axis. The seasons are caused by the tilt of the Earth's axis relative to its orbit around the sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, resulting in the changing seasons. When one hemisphere is tilted towards the sun, it experiences summer, while the other hemisphere is tilted away and experiences winter. As the Earth continues its orbit, the tilt gradually changes, leading to the transition of seasons.
