Phrase: Andean subduction system | Statement: [Nazca Plate, partOfSystem, Andean subduction system]

Target entity: Andean subduction system
Context triple: [Nazca Plate, partOfSystem, Andean subduction system]

• A. Tonga-Kermadec subduction system
  The Tonga-Kermadec subduction system is a major convergent plate boundary in the southwest Pacific where the Pacific Plate descends beneath the Indo-Australian Plate, producing one of the world’s deepest ocean trenches and most active seismic and volcanic regions.
• 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. Sumatra subduction zone
  The Sumatra subduction zone is a major convergent plate boundary off the western coast of Sumatra where intense seismic and volcanic activity occurs, including some of the world’s largest recorded earthquakes and tsunamis.
• D. Southern Uplands accretionary prism
  The Southern Uplands accretionary prism is a large, deformed wedge of sedimentary rocks in southern Scotland formed by the off-scraping and stacking of oceanic sediments during ancient subduction along the Iapetus Ocean.
• E. Cascadia Subduction Zone
  The Cascadia Subduction Zone is a major convergent plate boundary off the Pacific Northwest coast of North America, capable of generating powerful megathrust earthquakes and tsunamis.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: Andean subduction system
Triple: [Nazca Plate, partOfSystem, Andean subduction system]

The Andean subduction system is a major tectonic convergent margin along western South America where an oceanic plate descends beneath the continent, driving Andean mountain building, volcanism, and seismic activity.
