Equinoxes are the periods when :
Answer: D
At the equinoxes the sun shines equally on both Northern and Southern hemisphere.
Around 21 March and 23 September the Sun is directly overhead at the Equator. The circle of illumination then passes through both poles, so every latitude has about twelve hours of day and twelve of night, which is what 'equinox' (equal night) means.
The Sun is overhead at 23½°S, the Tropic of Capricorn, at the December solstice and at 23½°N, the Tropic of Cancer, at the June solstice. The Earth is nearest the Sun at perihelion in early January, which has nothing to do with the equinoxes.
