Answer:
The correct answer is option A.
Step-by-step explanation:
The seasons on earth, change as the Earth tilted on its axis, and revolve in a loop around the Sun every year. Summer takes place when the hemisphere tilted to the Sun, whereas winter takes place tilted away from the Sun. This tilting is the primary reason for the 4 seasons of the year - summer, autumn winter and spring.
Thus, the correct answer is option A.
