Answer:

I, II, III, and IV

Explanation:

    It was in 1912 that the first geologist elaborated a formal theory that the continents, at some point in geological history, would have been only one. He noted that some fossils, soil types, and vegetation were the same or similar in different regions of the earth separated by oceans.

   However, it was only after World War II (1939-1945) that the movement of the Tectonic Plates was scientifically discovered, the missing piece for proof that the continents were moving and had previously split. Over the years, scientists have been discovering and describing the stages of formation of the present form of the earth.
