Answer:
The presence of similar fossils(B) and rock formations(C) on several different continents supports the theory of Continental Drift.
Step-by-step explanation:
Alfred Wegener observed fossils of organisms that were not supposed to have survived in the climate of where they were found. Other key findings is that he found fossils of organisms that were found in one continent and the same fossils found on another continent whose edges seem to fit together.
He also observed rock formations or stratas of mountain ranges in one continent seem to fit together with another continent.
Added note:
Even if Alfred Wegener had these evidences to present, his theory of Continental Drift was rejected mainly because he could not explain the mechanism of how the super continent (Pangaea) split.
