Triple

Target entity: Friedmann–Lemaître–Robertson–Walker metric
Context triple: [Lambda-CDM model, basedOn, Friedmann–Lemaître–Robertson–Walker metric]

• A. Lemaître–Tolman metric
  The Lemaître–Tolman metric is an exact spherically symmetric, inhomogeneous solution of Einstein’s field equations used in cosmology to model non-uniform distributions of matter without assuming spatial homogeneity.
• B. FLRW cosmological models chosen
  FLRW cosmological models are a family of solutions to Einstein’s field equations that describe a homogeneous and isotropic expanding or contracting universe, forming the standard framework for modern cosmology.
• C. Gödel metric
  The Gödel metric is a solution to Einstein's field equations that describes a rotating universe allowing for closed timelike curves and thus the theoretical possibility of time travel.
• D. Lemaître–Hubble law
  The Lemaître–Hubble law is the fundamental cosmological relation that expresses the proportionality between a galaxy’s recessional velocity and its distance, providing the first observational evidence for the expansion of the universe.
• E. Reissner–Nordström metric
  The Reissner–Nordström metric is an exact solution in general relativity describing the spacetime geometry outside a static, spherically symmetric, electrically charged black hole.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
