Answer:
Winter
Explanation:
The picture shows the position of the Earth compared to the Sun around the June solstice, when the North Pole is closer to the Sun than the South one, that's Summer in the Northern Hemisphere.
Six months ago, the situation would be reversed... and then the Southern Pole would be closer to the Sun... and it would be Summer again, but in the Southern Hemisphere, and Winter in the Northern Hemisphere.
The question could have been six months in the future, with the same answer, since an orbit around the Sun takes a year.
