A The tilt of the Earth’s axis constantly changes between 0 and 23.5 degrees, giving us summer when the Earth is tilted more and winter when it is straight up.
B As the Earth goes around the Sun and the Earth’s axis remains pointed toward the North Celestial Pole, the Northern and Southern hemispheres alternately receive more and less direct sunlight.
C The Earth’s distance from the Sun varies, so that it is summer when we are closer to the Sun and winter when we are farther from the Sun.
D Seasons are caused by the periodic changes in the Sun’s surface temperature. When the temperature is highest, we have summer. When the temperature is lowest, we have winter.
E Seasons are caused by the influence of the planet Jupiter on our orbit.

B. The Earth's axis is tilted; the north and south hemispheres "take turns" getting more or less direct sunlight.

Probably the best answer is B.
Since these changes are the efect from the earth's yearly trip around the sun. Part of the year the earth's north pole points away from the sun and part of the time toward it. When the north pole points toward the sun, the sun's rays hit the northern half of the world more directly and it is summer. But when the north pole is pointed toward the sun, the south pole is pointed away. So the sun's light hits the earth at a less direct angle, spreading the warmth over a larger area, and it is winter.

B is right because direct sunlight is the key. The more overhead the sun, the more perpendicular the sunlight to the ground, the more heat is absorbed, which makes summer.
A is wrong because the axis is always tilted 23.5 degrees. It does not change. Think of the orbital path as a plane. The axis always makes an angle of 23.5 degrees with the orbital plane.
C is wrong because the change in distance is insignificant compared to the angle the sunlight makes with the ground.
D is wrong because the sun's surface temperature is relatively constant.
E is wrong because while Jupiter DOES affect the orbital path of the Earth, again, it is insignificant compared to the tilt of the axis.

Does Jupiter Have Seasons

Seasons are caused by two reasons.One is the tilt of the earth's axis and the other is the revolution of the earth around the sun.These two factors are covered in the answer "B".
So, "B" is the correct answer.
