Answer: Northern Hemisphere.
Step-by-step explanation:
The solstices are the dates of the year in which the sun reaches its maximum or minimum apparent distance from the sun in each hemisphere, in a negative angular way to the Earth's equator. There are two solstices, the summer solstice, and the winter solstice.
During the summer solstice, the sun reaches the minimum apparent distance from the earth, so the days are longer and the nights are shorter.
During the winter solstice, the sun reaches its maximum apparent distance from the earth, so the days are shorter and the nights are longer.
Due to the inclination of the earth, the solstices are opposite in each hemisphere, that is, when summer begins in the northern hemisphere, winter begins in the southern hemisphere.
