Context triple: [Messier 87, alsoKnownAs, 3C 274]
  • A. 3C 273
    3C 273 is a bright, nearby quasar in the constellation Virgo and one of the first quasars ever identified, making it a landmark object in extragalactic astronomy.
  • B. 3C 295
    3C 295 is a powerful, distant radio galaxy and X-ray–bright galaxy cluster often used as a calibration source in astronomical observations.
  • C. 3C 84
    3C 84 is a powerful radio-loud active galactic nucleus associated with the central galaxy NGC 1275 in the Perseus Cluster, notable for its strong jets and variable emission across the electromagnetic spectrum.
  • D. Cygnus X-3
    Cygnus X-3 is a powerful X-ray binary system in the constellation Cygnus, believed to consist of a compact object such as a black hole or neutron star orbiting a massive companion star and known for its intense X-ray and gamma-ray emissions.
  • E. Cygnus X-2
    Cygnus X-2 is a bright low-mass X-ray binary system in the constellation Cygnus, consisting of a neutron star accreting matter from a companion star and serving as an important source for studying X-ray emission and compact objects.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
