In the Northern Hemisphere, point A has which season?

Explanation:
The main idea is that seasons come from the tilt of Earth’s axis relative to its orbit around the Sun, which changes the Sun’s height in the sky and the length of daylight in a hemisphere. Point A corresponds to the moment when the Sun crosses the celestial equator from north to south, so day and night are about equal. This marks the start of fall in the Northern Hemisphere, after which days become shorter and the Sun stays lower in the sky. If the Sun were higher in the sky with longer days, it would be summer; if the Sun were lower with shorter days, it would be winter; and if days were lengthening after winter, it would be spring.
