The correct answer is A) Plant and animal fossils.
The evidence that Alfred Wegner had to support the existence of Pangaea was plant and animal fossils.
Geran scientist Alfred Wegner (1880-1931) developed the Earth once had just one huge mass of land or continent he called Pangea. We are talking millions of years ago. Due to continental drift and plate tectonics, the continent separated slowly through the years into the continents we know today. He based his affirmation on the many plants and human fossils found in different regions of the planet.
