He had thought this based on his observations, and based on this, this would actually be the reason to why he thought that this would be why the rocks would come together and join. He was first observing the fossils of glossopteris, which then he made a hypthosis first, and then he had concluded with facts and why this and that had happened. And therefore, your correct answer would then be (option b).
