The correct answer is B. The oceanic plate slides under the continental plate, and part of it melts to form magma that rises up through the continental plate.
Explanation
Subduction is a convergent activity between two tectonic plates, an oceanic and a continental one. In it, the heavier oceanic plate gets under the continental silver and melts into the mantle. This activity gives rise to ocean trenches, volcanoes, and island arches. According to the above, the correct answer is B. The oceanic plate slides under the continental plate, and part of it melts to form magma that rises up through the continental plate.
