How did wegener's theory of continental drift differ from the current theory of plate tectonics?

wegener's theory did not explain how the continents could move.
wegener's theory did not explain how the coastlines of continents were similar.
wegener's theory did not explain how continents' rock patterns could match.
wegener's theory did not explain how the fossils on different continents were similar.

The correct answer is Wegener's theory did not explain how the continents could move.

The theory given by Wegener's states that once the continents were once joined together but the continents are separated now. He was not able to tell the name of the force that made the continents apart. He did not have any explanation regarding the fact or the reason behind continental drift. The theory of plate tectonics on the other hand describes that the continents were broken down into slabs which moves as a result of movement of tectonic plates.

what are the choices?

we would need to see the picture to answer it
