In 1912, Alfred Wegener proposed the theory of continental drift, stating that all the continents were once joined together and slowly moved apart. However, his theory was not widely accepted in his time. In 1962, the discovery of sea floor spreading (sea floor being forced apart by the formation of new crust) eventually led to a more modern and widely accepted theory of plate tectonics.

a)

The theory of plate tectonics was a less complete theory because it failed to provide complete reasons and mechanisms for why the plates and continents moved.

b)

The theory of plate tectonics was a more complete theory because it provided a reason and mechanism for why the plates and continents moved.

c)

The theory of plate tectonics was a more complete theory because it failed to provide reasons and mechanisms for why the plates and continents moved.
