Question

wegener’s hypothesis of continental drift was finally confirmed by * 2 po fossils from the same reptile found on two continents continental coastlines that fit together evidence supporting the idea of sea-floor spreading the formation of mountain ranges such as the andes.

Explanation:

Wegener's continental drift hypothesis was initially based on evidence like matching coastlines and similar fossils, but the key confirmation came from the discovery of sea - floor spreading. Sea - floor spreading provided the mechanism (convection currents in the mantle driving the movement of oceanic crust, which in turn moves the continents) that explained how continents could drift. Matching coastlines and similar fossils were early supportive evidence, and mountain formation (like the Andes) is related to plate tectonics (a more developed theory from continental drift) but not the confirmation of continental drift itself. So the evidence of sea - floor spreading was what finally confirmed Wegener's hypothesis.

Answer:

the option "evidence supporting the idea of sea - floor spreading"
