Geologists discovered that the largest coal deposits were formed around 300 million years ago. How did this observation support the theory of plate tectonics?(1 point)

Responses

Around that time, those regions were located on arid plateaus in temperate regions.
Around that time, those regions were located on arid plateaus in temperate regions.

Around that time, those regions were located near the south pole where coal would likely have formed.
Around that time, those regions were located near the south pole where coal would likely have formed.

Around that time, it is thought that those regions were located along the ridge of a long mountain chain.
