Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Friedmann–Robertson–Walker cosmology | Statement: [Gravitation and Cosmology, subject, Friedmann–Robertson–Walker cosmology]

Target entity: Friedmann–Robertson–Walker cosmology
Context triple: [Gravitation and Cosmology, subject, Friedmann–Robertson–Walker cosmology]

• A. 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.
• B. 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.
• C. 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.
• D. steady-state cosmology
  Steady-state cosmology is a now largely discredited cosmological model proposing an eternal, unchanging universe in which new matter is continuously created to maintain constant density despite expansion.
• E. Bianchi type cosmologies
  Bianchi type cosmologies are a class of spatially homogeneous but generally anisotropic cosmological models that classify possible three-dimensional Lie group symmetries of spacetime in general relativity.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
