Phrase: Izu–Bonin–Mariana subduction system | Statement: [Izu–Bonin Arc, partOf, Izu–Bonin–Mariana subduction system]

Target entity: Izu–Bonin–Mariana subduction system
Context triple: [Izu–Bonin Arc, partOf, Izu–Bonin–Mariana subduction system]

• A. Mariana subduction zone
  The Mariana subduction zone is a deep oceanic trench system in the western Pacific where the Pacific Plate is forced beneath the smaller Mariana Plate, creating one of the world's deepest and most active tectonic boundaries.
• B. Kuril–Kamchatka subduction system
  The Kuril–Kamchatka subduction system is a major convergent plate boundary in the northwest Pacific where the Pacific Plate subducts beneath the Okhotsk Plate, generating intense seismic activity and extensive volcanism along the Kuril Islands and Kamchatka Peninsula.
• C. Sunda subduction system
  The Sunda subduction system is a major convergent plate boundary in Southeast Asia where the Indo-Australian Plate is being subducted beneath the Eurasian/Sunda Plate, generating intense seismic and volcanic activity along Indonesia’s island arcs.
• D. 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.
• 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
• G. Unsure - the case is ambiguous/there is not enough information to decide.
