Question

which piece of evidence suggests that africa and south america formed gondwanaland 200 million years ago? coal fields a shared ocean folded mountains land formations created by glaciers

Explanation:

Folded mountains on the coasts of Africa and South - America match up, indicating they were once part of the same landmass, Gondwanaland. Coal fields can be found in other regions too and don't uniquely prove the connection. A shared ocean is not evidence of them being joined. Glacial land - formations are not the key evidence for their past connection.

Answer:

folded mountains
