Part A:
The answer to Part A is D. Spring.
Part B:
The answer to Part B is C. The Northern Hemisphere is receiving direct sunlight at Position C. During the spring equinox, which occurs around March 20th, both the Northern and Southern Hemispheres receive an equal amount of direct sunlight as the Earth's axis is not tilted towards or away from the Sun. This means that the Northern Hemisphere is not tilted away from the Sun at Position C, which eliminates option B. Additionally, the Northern Hemisphere is not experiencing nighttime at Position C as it is receiving direct sunlight, which eliminates option A. Option D is also incorrect as the Earth's distance from the Sun does not affect the seasons
