The correct answer is option (B) continental drift.
Continental drift is a theory explaining the movement of the earth’s continents over the geological time scale, drifting across the ocean bed. It was proposed by Alfred Wegener in 1912. Similar plants and animal fossils found around the shores of the different continents suggests that these continents were once joined as a single super continent named Pangaea. This Pangaea broke up long ago and the continents moved to their current positions. The ancient fossils of the same species of plants and animals were found on rocks of the same age but on the continents that are now widely separated.
The experiment could be repeated unnecessarily, or their work could be stolen if it is not communicated

I would answer your question but i think you wanted to add options. next time you can just screen shot and actually i think you still can by pressing the edit button. And there are several types of wedges you could be talking about mechanical, frost, salt, etc.
You need to be a bit more specific. but i would be more than happy to answer your question. :)
