Final answer:
The true statement is that both the Northern and Southern hemispheres receive the same amount of sunlight on the equinoxes.
Step-by-step explanation:
The statement that is true among the options provided is: A. Both the Northern and Southern hemispheres receive the same amount of sunlight on the equinoxes. This is because on the equinoxes, which occur around March 21 and September 21, the Sun is on the celestial equator and every place on Earth experiences roughly 12 hours of sunshine and 12 hours of night. The Sun appears above our planet's equator and neither hemisphere is favored, resulting in equal day and night durations. During the summer solstice, which happens around June 21, the Northern Hemisphere receives the most direct sunlight as the Sun shines down most directly upon it. This is when the Sun is at the zenith for observers on the Tropic of Cancer. Conversely, during the winter solstice in December, it's the Southern Hemisphere that leans into the Sun and receives the most direct sunlight.
