Phrase: Ryukyu forearc | Statement: [Ryukyu subduction zone, hasFeature, Ryukyu forearc]

Target entity: Ryukyu forearc
Context triple: [Ryukyu subduction zone, hasFeature, Ryukyu forearc]

• A. 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.
• 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. Southwest Japan Arc
  The Southwest Japan Arc is a major volcanic and tectonic arc in southwestern Japan, characterized by active volcanoes such as Mount Aso and formed by the subduction of oceanic plates beneath the Eurasian Plate.
• D. 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.
• E. 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.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: Ryukyu forearc
Triple: [Ryukyu subduction zone, hasFeature, Ryukyu forearc]

The Ryukyu forearc is the tectonically active region between the Ryukyu Trench and the Ryukyu island arc, characterized by intense seismicity, deformation, and sediment accretion associated with the subduction of the Philippine Sea Plate beneath the Eurasian Plate.
