Answer:
The answer is letter A, At some point, the land masses were connected to each other.
Explanation:
The answer is related to the Theory of Continental Drift by Alfred Wegener, a famous geophycisist and metereologist. He proposed that long time ago, the earth was a supercontinent, which means everything was connected to each other. This was called the "Pangaea." This allowed prehistoric animals to exist on different parts of the earth. This explains why same freshwater reptile species in South Africa can also be found in Southern America and these are proven by the fossils found. However, due to continental drifting, the Pangaea broke up and resulted to the movement of the Earth's different plates.
