Answer:
the last picture
Step-by-step explanation:
The picture that shows the position of Earth during summer in South Carolina would be the last picture, I highlighted it in red below. South Carolina is located in North America. Summer is the hottest time of the year because it is when your location is closest to the sun. Which in the pictures provided the only one in which North America is closest to the sun is the last picture. Also the earth rotates on an inclined axis so pictures 2 and 3 would not be valid.
