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: Fermi gas | Statement: [Wigner-Seitz radius r_s, relatedTo, Fermi gas]

Target entity: Fermi gas
Context triple: [Wigner-Seitz radius r_s, relatedTo, Fermi gas]

• A. Fermi gas chosen
  A Fermi gas is a quantum many-particle system composed of fermions that obey Fermi–Dirac statistics, often used to model electrons in metals, neutrons in neutron stars, and ultracold atomic gases.
• B. Fermi liquid theory
  Fermi liquid theory is a framework in condensed matter physics that describes how interacting fermions in a metal behave like long-lived quasiparticles with properties similar to those of a non-interacting Fermi gas.
• C. Bose gas
  A Bose gas is a quantum-mechanical system of indistinguishable bosons whose collective behavior is governed by Bose–Einstein statistics, often leading to phenomena like Bose–Einstein condensation at low temperatures.
• D. Fermi–Dirac statistics
  Fermi–Dirac statistics is the quantum statistical framework that describes the distribution and behavior of indistinguishable fermions, such as electrons, which obey the Pauli exclusion principle.
• E. Migdal theorem on Fermi systems
  Migdal theorem on Fermi systems is a result in many-body quantum theory that justifies neglecting certain vertex corrections in strongly interacting Fermi systems, enabling controlled calculations of quasiparticle properties.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
