September and December
Answer is Wrong!
Answer is Right!
The correct answer is C. March and September.
An equinox is a day in the year when the Sun crosses the equator, and day and night are of equal length. There are two equinoxes each year, in March and September.
The March equinox, also known as the vernal equinox, occurs on March 20 or 21. It marks the beginning of spring in the Northern Hemisphere and autumn in the Southern Hemisphere.
The September equinox, also known as the autumnal equinox, occurs on September 22 or 23. It marks the beginning of autumn in the Northern Hemisphere and spring in the Southern Hemisphere.
The options A, B, and D are incorrect because they do not correspond to the dates of the equinoxes.
