A)The fit of continents together.
C. alternating symmetrical patterns of paleomagnetism on the seafloor
The primary evidence that convinced geologists of continental movement is the fit of continents, notably described by Alfred Wegener. He highlighted how the shapes of coastlines, along with matching geological and fossil records, indicated that continents were once part of a single landmass. This, along with other geological studies, helped establish the concept of plate tectonics and continental drift.
