Look at this image. Which explanation best summarizes the hypothesis shown in the figure?

• The present continents will gradually move to form a single landmass called Pangaea.

• The continents were once a large landmass name Pangaea, which broke apart and gradually drifted to the present-day locations of the continents.

• The continents were once a large landmass, but the north and south magnetic poles pulled the continents apart toward the poles

• The continents were once a large landmass, but the ocean levels rose, and these oceans separate today's continents.
