The correct answer is option C. "its axis is tilted".
Explanation:
The axis of the Earth is tilted at an angle of 23.5 degrees away from vertical, perpendicular to the plane. This tilt results in the Earth receiving different amounts of energy from the Sun in each hemisphere and having its characteristic seasons. This phenomena is explained by how the Earth responds to its axis being tilted, which is by traveling in a loop around the Sun each year.
