An island arc comprising of volcanic islands forms as a result of ocean-ocean convergence.

Question

Quizplus · Accepted Answer

Island arcs are commonly formed at subduction zones where one tectonic plate with oceanic crust subducts beneath another plate with oceanic crust. The subducting plate melts and generates magma that rises to the surface to form a chain of volcanic islands, known as an island arc. This process is typically associated with ocean-ocean convergence. Therefore, statement A is correct.
