The correct answer is A) The continents were once connected.
The affirmation suggests that the continents of Africa and South America were once connected.
Fossils of a now extinct dinosaur have been found near the East coast of South America and the West Coast of Africa. The dinosaur could not swim or fly. That is why this suggests that the continents of Africa and South America were once connected.
The theory of Pangea suggests that 300 million years ago, planet Earth had only one enormous mass of land that scientists have identified as Pangea Continent. This big portion of land was surrounded by sea. Scientists have named that sea Panthalassa. That is why fossils of a now extinct dinosaur can be found near the East coast of South America and the West Coast of Africa. As the dinosaur could not swim or fly, scientists that believe in the existence of Pangea suggest that the continents of Africa and South America were once connected.
