For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Antiproton Decelerator (historically via previous antiproton complex) | Statement: [Proton Synchrotron, feedsBeamTo, Antiproton Decelerator (historically via previous antiproton complex)]

Target entity: Antiproton Decelerator (historically via previous antiproton complex)
Context triple: [Proton Synchrotron, feedsBeamTo, Antiproton Decelerator (historically via previous antiproton complex)]

• A. Antiproton Decelerator chosen
  The Antiproton Decelerator is a specialized CERN facility that slows down antiprotons to low energies for precision experiments in antimatter physics.
• B. Proton Synchrotron Booster
  The Proton Synchrotron Booster is a circular particle accelerator at CERN that increases the energy of protons from the linear accelerator before injecting them into larger synchrotrons in the accelerator complex.
• C. Proton Synchrotron
  The Proton Synchrotron is a historic circular particle accelerator at CERN that has played a key role in high-energy physics research and in feeding beams to larger colliders.
• D. CERN accelerator complex
  The CERN accelerator complex is a network of interconnected particle accelerators and beamlines near Geneva that produce and prepare high-energy particle beams for experiments such as those at the Large Hadron Collider.
• E. Linac2
  Linac2 was CERN’s long-serving linear accelerator that pre-accelerated protons for injection into the Proton Synchrotron Booster and the rest of the accelerator complex before being superseded by Linac4.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
