Answer:
The correct answer is D.
Explanation:
In volcanic regions, as the molten magma flows out onto the seafloor creating new beds, the faster it flows, the less steep the mid-ocean ridge is. If however, it is slow-flowing, then oceanic lithosphere formed cool closer to the ridge axis thus making it very steep.
