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 models | Statement: [Principles of Physical Cosmology, topic, Friedmann–Robertson–Walker models]

Target entity: Friedmann–Robertson–Walker models
Context triple: [Principles of Physical Cosmology, topic, Friedmann–Robertson–Walker models]

• 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. Milne universe model
  The Milne universe model is a cosmological model that describes an empty, expanding universe with negative spatial curvature, serving as a special-relativistic alternative to general relativistic cosmologies.
• C. 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.
• D. 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.
• E. Einstein static universe
  The Einstein static universe is a cosmological model proposed by Albert Einstein in which the universe is finite, spatially curved, and static, balanced by a cosmological constant that counteracts gravitational collapse.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
