D)rise of magma along transform faults.
E)mantle plumes.

Question

Quizplus · Accepted Answer

The Pacific Ring of Fire is primarily composed of subduction zones where one tectonic plate slides beneath another, causing melting of the material in the mantle. This melting produces magma, which rises to the surface and fuels volcanic activity. Therefore, the magma which fuels and produces the volcanic activity around the Pacific Ring of Fire is derived from the rise of material that was melted in subduction zones along the Pacific margins, making option B the best choice.
