Alfred Wegener's original theory of continental drift, proposed in 1912, primarily relied on several pieces of evidence that were available at the time. Among the options you've provided, the one that Wegener had access to was:

**mountains in North America appearing to match up with mountains in Northern Europe.**

Wegener noted geological similarities, including mountain ranges and rock formations on different continents that suggested they were once connected. The other evidence, such as seafloor spreading, reversing paleomagnetism, and details about the geologically active seafloor, were discovered and understood much later, after Wegener's time.
