Alfred wegener believed that all of the continents were originally:
a.
a single landmass called pangaea
c.
three landmasses called europe, asia, and gondwana
b.
two landmasses called eurasia and gondwana
d.
none of the above

Alfred Wegener believed that all of the continents were originally attached! By looking at the map, you can see that Africa and South America look like they were once joined. This 'super continent' was known as Pangaea. He also found fossils that proved his point.
Hope this helps :)
