Alfred Wegener cited the following pieces of evidence to support his hypothesis of continental drift:
- The continents fit together like a puzzle.
- Similar fossils have been found at different continents.
- Similar rock formations and mountain ranges on different continents.
The statement about "New oceanic crust formed between the northern and southern continents, pushing them apart" relates more to the theory of plate tectonics that came later, not directly to Wegener's original hypothesis of continental drift. The same applies to the statement about the contraction of the Earth.
So, the correct answer is:
The continents fit together like a puzzle.
