Which continents contain folded mountains that match up to form one continuous mountain chain, serving as evidence that they once belonged to one landmass called pangaea? antarctica and africa africa and north america south america and africa eurasia and south america

The correct answer is South America and Africa.

South America and Africa are two continents  where two or more Earth’s tectonic plates are pushed together to form the Fold Mountains.  By colliding, compressing boundaries, rocks and debris are warped and folded into mountains. Fold Mountains are created through a process called orogeny. An orogenic event takes millions of years to create a fold mountain. They are created at convergent plate boundaries, sometimes called continental collision zones or compression zones.  

The answer is C, South America and Africa :)
