Which piece of evidence supported Wegener's hypothesis of continental drift?

Wegener's hypothesis of continental drift was primarily supported by the observation that Southern continental landmasses, such as South America and Africa, exhibit a complementary fit, similar to puzzle pieces. This visual evidence suggested that these continents were once joined and have since drifted apart over geological time. The resemblance of coastlines and matching geologic formations and fossils across continents further substantiated his claim, indicating a historical connection that would not exist if the continents had always been in their current positions.

The other options do not support Wegener's ideas. For instance, the notion that continents are stationary directly contradicts his hypothesis. Ocean currents and the Earth's rotation may influence climate and other geological processes, but they do not provide specific evidence of how continents were once contiguous and have since moved apart. Therefore, the geological and geographical alignment of continents is the most compelling evidence supporting the concept of continental drift.
