Answer:
C. They were warm climate plants that would not grow in a cold pilot area
Step-by-step explanation:
These plant fossils they found in Svalbard in Norway were tree stumps of an ancient forest. They were said to have originally grown near the equator, so it was a tropical forest. However these fossils were found up north, where they could not have grown due to the climate. This showed that continental drift carried these trees to the north, in the colder region, which is now Norway.
