Answer:
D
Explanation:
The ring of fire has very large amount of plate collision so it cannot be B.
It can't be A either because the ring of fire has nothing to do with radioactive element decay.
The two main things with the ring of fire is the fact that there are a lot of volcanos and earthquakes, so it cannot be C.
Since the ring of fire has so many collisions of plates, and none of the other answers are correct, the answer is D.
Hope this helps!
