Quizplus · Accepted Answer

Site A is located at a convergent plate boundary where an oceanic plate is subducting beneath a continental plate. This type of boundary is characterized by the presence of a trench and an accretionary prism, which are formed by the compression and deformation of the sedimentary rocks that accumulate at the base of the continental slope. As the oceanic plate continues to subduct, it may eventually be accreted onto the continental plate, leading to the formation of a volcanic mountain belt and a nearby fold and thrust belt. However, at the current stage of development shown in the image, these features have not yet formed. Therefore, the best choice is B.
