  • A. GW170814
    GW170814 is a gravitational-wave signal detected in 2017 from the merger of two stellar-mass black holes, notable for being observed jointly by the LIGO and Virgo detectors.
  • B. GW150914
    GW150914 is the first directly detected gravitational-wave signal, produced by the merger of two stellar-mass black holes and marking the beginning of gravitational-wave astronomy.
  • C. LIGO–Virgo–KAGRA network
    The LIGO–Virgo–KAGRA network is an international collaboration of ground-based gravitational-wave observatories that jointly detect and analyze ripples in spacetime from cosmic events like merging black holes and neutron stars.
  • D. IGO
    IGO is the ICAO airline designator for IndiGo, a major low-cost carrier based in India.
  • E. LIGO Scientific Collaboration
    The LIGO Scientific Collaboration is an international group of scientists and institutions that built and operate the LIGO detectors and made the first direct detection of gravitational waves, confirming a key prediction of Einstein’s general relativity.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
