"Glossopteris plants had bulky seeds."

Reason: If the seeds were large and not easily carried by wind or water, the only reasonable way the same plant could appear on widely separated continents is that those landmasses were once joined. The other choices do not directly explain why identical plant fossils occur on different continents.
