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.
