Modern scientists believe that the continents:

A. have never moved

B. have stopped moving

C. were once one big land mass

D. will eventually rejoin each other

So it looks like A and B are definitely not the answer. I know that most people believe in Pangea, a supercontinent, and that the continents were once a large landmass, but I don't really know anything about if people believe they will rejoin again.

They believe C. were once a big landmass, and that earthquakes and other natural disasters separated them
