LNGS underground halls

Target entity: LNGS underground halls
Context triple: [OPERA, sitedIn, LNGS underground halls]

• A. LHC service tunnels
  The LHC service tunnels are auxiliary underground passages at CERN that house infrastructure and provide access and support to the Large Hadron Collider’s main accelerator ring.
• B. CMS experimental cavern
  The CMS experimental cavern is the large underground facility at CERN that houses the Compact Muon Solenoid detector for high-energy particle collision experiments at the Large Hadron Collider.
• C. Sanford Underground Research Facility
  The Sanford Underground Research Facility is a deep underground laboratory in South Dakota that hosts major particle physics and astrophysics experiments, including serving as the far-site for the DUNE neutrino project.
• D. CERN control centre
  The CERN Control Centre is the central facility from which scientists and engineers operate and monitor CERN’s particle accelerators and associated experiments.
• E. CERN Large Hadron Collider surface facilities
  The CERN Large Hadron Collider surface facilities are the above-ground buildings and infrastructure that support and control the LHC’s particle physics experiments near Geneva.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
