Subduction is the process in which one tectonic plate moves beneath another tectonic plate. In this figure, we can see that the Nazca Plate is moving beneath the South American Plate, which indicates that subduction is occurring. The location where this subduction is happening is marked as letter B, which is the boundary between the Nazca Plate and the South American Plate. Therefore, the correct answer is B.
