Phrase: Izu–Bonin–Mariana back-arc region | Statement: [Izu–Bonin–Mariana Trench system, relatedTo, Izu–Bonin–Mariana back-arc region]

Target entity: Izu–Bonin–Mariana back-arc region
Context triple: [Izu–Bonin–Mariana Trench system, relatedTo, Izu–Bonin–Mariana back-arc region]

• A. Ryukyu back-arc basin
  The Ryukyu back-arc basin is a seafloor spreading region behind the Ryukyu island arc, formed by the subduction of the Philippine Sea Plate beneath the Eurasian Plate and characterized by active tectonism and volcanism.
• B. Izu–Bonin Arc
  The Izu–Bonin Arc is a volcanic island arc in the western Pacific Ocean formed by subduction along the boundary of the Philippine Sea Plate, stretching south from Japan’s Izu Peninsula toward the Mariana Islands.
• C. Ryukyu subduction zone
  The Ryukyu subduction zone is a tectonic plate boundary south of Japan where an oceanic plate descends beneath the Okinawa Plate, generating frequent earthquakes, volcanism, and the Ryukyu island arc.
• D. Izu–Bonin–Mariana Trench system
  The Izu–Bonin–Mariana Trench system is a major convergent plate boundary in the western Pacific Ocean, forming one of the world’s deepest and most extensive oceanic trench complexes associated with intense subduction and seismic activity.
• E. Kyushu–Palau Ridge system
  The Kyushu–Palau Ridge system is a major underwater volcanic island arc and tectonic ridge in the Philippine Sea, formed by subduction-related processes along the western Pacific margin.
• F. None of above. chosen
