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: Hu–Sawicki f(R) model | Statement: [f(R) gravity, hasExample, Hu–Sawicki f(R) model]

Target entity: Hu–Sawicki f(R) model
Context triple: [f(R) gravity, hasExample, Hu–Sawicki f(R) model]

• A. f(R) gravity chosen
  f(R) gravity is a class of modified theories of gravity in which the Einstein–Hilbert action is generalized by replacing the Ricci scalar R with a function f(R), leading to alternative explanations for cosmic acceleration and gravitational phenomena.
• B. FLRW cosmological models
  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. Brans–Dicke theory
  Brans–Dicke theory is an alternative theory of gravitation to Einstein’s general relativity that introduces a scalar field to allow for a varying gravitational “constant.”
• D. Starobinsky R^2 inflation model
  The Starobinsky R² inflation model is a pioneering cosmological model of the early universe in which inflation is driven by a modification of general relativity that adds a term proportional to the square of the Ricci scalar to the gravitational action.
• 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.
