Which volcanic outcome develops during oceanic slab subduction?

A)Formation of an island arc
B)Development of a rift valley
C)Creation of abyssal plains
D)Generation of transform faults

💡 Explanation

An island arc arises due to flux melting; subducting oceanic slabs release fluids, lowering the mantle's melting point. This generates magma that rises and forms volcanoes, therefore creating island arcs rather than rifts or plains because of subduction induced volcanic activity.
