Answer:
12 hours
Explanation:
During the autumnal equinox, which occurs around September 22nd or 23rd, the North Pole receives approximately 12 hours of daylight and 12 hours of darkness. This is because during the equinoxes, the tilt of the Earth's axis is such that the entire planet experiences roughly equal lengths of day and night. So, the correct answer is a) 12 hours.
