According to the theory of continental drift, why do the coastlines of Africa and South America appear to fit together so well?

• Africa and South America used to be joined together, but split apart long ago.

• Africa and South America are drifting towards each other and will soon fit together perfectly.

• Ocean currents on either side of the Atlantic have eroded the coastlines into the same shape.

• The theory does not explain why the coastlines seem to match.
