D
Correct answer
Explanation
The equator experiences the least seasonal variation in temperature and daylight hours throughout the year. This is because the equator receives fairly consistent solar radiation year-round, unlike higher latitudes where the angle of sunlight changes dramatically with seasons. At the Arctic Circle, seasonal variation is most extreme with periods of continuous daylight or darkness depending on the season.
