d. new ocean ridges and seafloor

D. New ocean ridges and seafloor: When two plates separate from each other, all the magma inside the Earth rises to the surface and pushes the tectonic plates, creating a new crust in that area. New sea floor is created, having as examples the limit of the so-called Mesoatlantic Ridge, which separates the North American and Euroasian plates in the north of the planet, and in the south, in the Atlantic Ocean, separates the African and South American plates. They are regions where new sea floor is always created.
