Why was Alfred Wegner's theory of continental drift not widely accepted by the scientific community at first? A
He had no evidence to support it.

B
The continents were not moving at that time.

C
The shape of the continents did not match up.

D
He could not explain how the continents move.

I think it’s B but I’m not 100% sure, The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.

It’s d because he couldn’t explain what made the continents move
