An island arc is a long chain of volcanic islands that are formed on the margin of a continent where oceanic crust is subducting beneath oceanic crust. The other options are not specific to this type of formation. The Wadati-Benioff zone refers to the region where earthquakes occur along a subduction zone. A continental arc is a chain of volcanic mountains that form parallel to a subduction zone, but on the overriding continental plate. A hotspot track is a chain of volcanic islands or seamounts that form over a stationary hotspot in the mantle.
