How does the distribution of the world's major coal reserves support the theory of plate tectonics? (1 point)

a) around the time that the continents were together as pangaea, the regions where coal developed were located along the ridge of a long mountain chain.

b) around 300 million years ago, the regions where coal formed were located in tropical climates that were partially submerged on the coasts.

c) before the formation of pangaea, the regions where coal developed were on arid plateaus in temperate regions.

d) around 65 million years ago, the regions where coal formed were near the south pole where coal would likely have formed.
