What was the main objection to Alfred Wegener's continental drift hypothesis?

• The continents were too large to have ever been connected.

• There was no evidence to support the movement of continents.

• Wegener did not provide a mechanism for the continents to move.

• The theory suggested that continents moved too quickly.
