Answer:
Both A and C are true.
Step-by-step explanation:
Due to the inclination of Earth in its own axis. When our planet surrounds the sun in its own orbit. When is Equinox, the same amount of sunlight is distributed in the Northern and Southern hemisphere. The prefix, equi, means the same.
When is June solstice, because of this inclination, the sunlight goes directly to the Northern hemisphere, that is the reason in this part of the Earth, the countries have hot summer, on the other hand, the South countries have cold summer, like Argentina or Chile.
