Answer:
Option (C)
Explanation:
The continental drift theory was introduced by Alfred Wegener. He said that the continents moved over the vast ocean surface from one place to another.
He contributed many pieces of evidences in support f this theory, which includes the founding of similar fossil assemblages, similar rocks types in the distant continents, matching of the continental boundaries, but he was not able to explain the main mechanism behind the continental motion.
Due to this, this theory was not accepted by the other scientists and he was criticized by them.
Later, this theory was modified into the Plate tectonic theory which was successful in explaining the mechanism behind the continental motion i.e the formation of convection current in mantle that drives the plates movement.
Thus, the correct answer is option (C).
