A) Asia rifted apart from Europe
B) Africa and North America collided to form the Appalachian Mountains

D) South America rifted apart from Africa
E) none of these

The South Atlantic Ocean formed when South America and Africa, which were once part of the supercontinent Gondwana, rifted apart from each other. This process began in the Jurassic period, around 150 million years ago, and led to the formation of the South Atlantic Ocean as the continental plates moved apart.
