Answer:
The correct option is: A) As Earth goes around the Sun and Earth's axis remains pointed toward Polaris, the Northern and Southern hemispheres alternately receive more and less direct sunlight.
Explanation:
Seasons on Earth are the changes in the weather caused due to the titled axis of the Earth, relative to the orbital or ecliptic plane, while orbiting around the Sun. The Earth's axis of rotation is tilted approximately by an angle of 23.4°.
This results in the change in the intensity of the sunlight received by the Earth's surface, due to which the southern and the northern hemispheres experience opposite seasons.
