Answer:
Option D, Continents cannot cut through the ocean floor.
Explanation:
It was believed earlier that oceans were the land bridges that used to connect different geologic plates of planet earth earlier, had now sank down and thus there exists no connection between the tectonic plates. Therefore, without any link or connection, continents cannot cut through the ocean floor.
