Which statement correctly summarizes Wegener’s theory of continental drift?

All seven continents have always been in the same locations on Earth as they are today.
When a meteorite crashed onto the planet, it broke the giant supercontinent Pangaea into smaller landmasses.
The seven continents on Earth drifted until they formed one giant supercontinent, which Wegener called Pangaea.
Over tens of millions of years, the giant supercontinent Pangaea began to slowly drift apart, forming the continents as they are known today.
