Answer:
Option B
The continents were once connected as one landmass.
Step-by-step explanation:
The theory of continental drift suggests that all the continents on the planet were once connected, forming a supercontinent. However, over time they drifted apart as a result of some internal forces of the earth.
The most appropriate option that shows this is option B: The continents were once connected as one landmass.
This statement describes one of Alfred Wegener's ideas that suggests that a very long time ago, the continents were once connected in a landlocked mass. The fact that the continents are separated now shows that the continents are continuously shifting position on the earth's surface.
