At a certain time of the year, the South Pole receives constant sunlight and the days are 24 hours long. Why does this occur?

A: The Sun moves slightly south of Earth due to a magnetic pull received from other planets.

B: Earth's magnetic field reverses and diverts light rays towards the Southern Hemisphere.

C: Earth's axis tilts the Southern Hemisphere toward the Sun, reducing the effects of day and night from Earth's rotation.

D: the hole in Earth's ozone moves over the South Pole, allowing light rays to completely penetrate the atmosphere.
