Answer:
Options (1), (2) and (3)
Explanation:
Alfred Wegener was the person who first invented the continental drift theory. He observed that the continents move from one place to another with respect to a fixed point. He put forward many pieces of evidence but he was unable to explain the main mechanism that is responsible for these motion of continents.
The pieces of evidence that were given by Alfred Wegener supporting the continental drift theory are-
(a) The continents move slowly and continuously from one place to another and the edges of these continents perfectly match with the other.
(b) Similar fossil assemblages were found in currently separated continents.
(c) Similar rock types are also found and suggested that the continents were once all together forming a huge landmass which is known as the Pangaea.
Later this theory was modified into a more simple and universally accepted theory which is commonly known as the Plate tectonic theory.
Hence, the correct answers are options (1), (2) and (3).
