The feature that creates a zigzag pattern on the seafloor is a mid-ocean ridge, which is a type of underwater mountain range formed by tectonic plates pulling apart from each other. This produces a zigzag pattern as the plates move and create new seafloor. The other options (island arc, linear island chain, and subduction zone) do not typically produce a zigzag pattern on the seafloor.
