I think it's D, end of summer
Because there are 2 equinoxes, 1 later in the spring and 1 around the middle of autumn. Which means I don't think it's A, B, or C. But it is around the end of summer. That's what I think the answer is. But, summer ends when autumn starts so... it could be B.
Hope this helps a little.
