Phrase: PEP-II | Statement: [PEP-II storage ring, hasAbbreviation, PEP-II]

Target entity: PEP-II
Context triple: [PEP-II storage ring, hasAbbreviation, PEP-II]

• A. PEP-II storage ring chosen
  The PEP-II storage ring was an asymmetric-energy electron–positron collider at SLAC designed to produce large numbers of B mesons for precision studies of CP violation and other aspects of particle physics.
• B. LCLS-II
  LCLS-II is an advanced next-generation X-ray free-electron laser facility designed to produce extremely bright, ultrafast X-ray pulses for cutting-edge scientific research.
• C. Low Energy Antiproton Ring
  The Low Energy Antiproton Ring (LEAR) was a CERN storage ring designed to decelerate and store antiprotons at low energies for precision experiments in antimatter physics.
• D. Antiproton Accumulator
  The Antiproton Accumulator was a storage and cooling ring at CERN designed to collect, cool, and accumulate antiprotons for high-energy proton–antiproton collision experiments.
• E. SPEAR storage ring
  The SPEAR storage ring is an electron storage ring at SLAC National Accelerator Laboratory that historically served as both a particle physics collider and a synchrotron radiation source, forming the basis for later upgrades like SPEAR3.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
