I gave my students this multiple choice question: Which is a reason for Arkansas having multiple seasons?

Only one answer is correct among these 4 choices:
- the tilt of Earth's axis
- the speed of Earth's orbit
- Earth's distance from the Sun
- Earth gravitational pull toward the Moon

Could you tell me which one is correct?
