Triple

Target entity: international linear collider R&D
Context triple: [Linear Collider Collaboration, coordinates, international linear collider R&D]

• A. International Linear Collider chosen
  The International Linear Collider is a proposed high-energy electron–positron linear accelerator designed to complement the Large Hadron Collider by enabling precise studies of fundamental particles and forces.
• B. Compact Linear Collider
  The Compact Linear Collider is a proposed high-energy electron–positron linear collider at CERN designed to explore physics beyond the Standard Model with multi-TeV collisions.
• C. Compact Linear Collider test facilities
  The Compact Linear Collider test facilities are experimental research installations at CERN dedicated to developing and validating technologies for a future high-energy electron–positron linear collider.
• D. Linear Collider Conceptual Design Report
  The Linear Collider Conceptual Design Report is a foundational document outlining the scientific goals, design principles, and feasibility studies for a proposed high-energy linear particle collider.
• E. Linear Collider Collaboration
  The Linear Collider Collaboration is an international scientific consortium that coordinates global research and development efforts for future linear particle collider projects.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
