Target entity: Phobos coordinate system
Context triple: [Roche crater, hasCoordinateSystem, Phobos coordinate system]

• A. PHOBOS
  PHOBOS was a high-energy nuclear physics experiment at the Relativistic Heavy Ion Collider designed to study particle production and properties of quark–gluon plasma in heavy-ion collisions.
• B. Mercury coordinate system
  The Mercury coordinate system is a standardized planetary reference framework used to map and describe locations on the surface of the planet Mercury.
• C. Mars system
  The Mars system comprises the planet Mars, its moons Phobos and Deimos, and the surrounding space and smaller bodies gravitationally bound to it.
• D. JPL HORIZONS system
  The JPL HORIZONS system is an online ephemeris service provided by NASA’s Jet Propulsion Laboratory that generates highly accurate positions and orbital data for solar system bodies, spacecraft, and other objects.
• E. Phobos
  Phobos is the larger and innermost of Mars’s two small, irregularly shaped moons, known for its rapid orbit and heavily cratered surface.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
