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: Navier–Stokes equations | Statement: [Rayleigh–Bénard convection, governedBy, Navier–Stokes equations]

Target entity: Navier–Stokes equations
Context triple: [Rayleigh–Bénard convection, governedBy, Navier–Stokes equations]

• A. Navier–Stokes equations chosen
  The Navier–Stokes equations are fundamental partial differential equations in fluid mechanics that describe how the velocity field of a fluid evolves under forces like pressure and viscosity.
• B. Euler equations
  The Euler equations are fundamental partial differential equations in fluid dynamics that describe the motion of an ideal (inviscid) fluid without viscosity.
• C. Navier–Cauchy equations
  The Navier–Cauchy equations are the fundamental partial differential equations in linear elasticity that describe how stresses and displacements are related within deformable solid materials.
• D. Stokes flow
  Stokes flow is a type of fluid motion dominated by viscous forces and characterized by very low Reynolds numbers, where inertial effects are negligible.
• E. Navier–Stokes existence and smoothness problem
  The Navier–Stokes existence and smoothness problem is a fundamental unsolved question in mathematical fluid dynamics that asks whether three-dimensional fluid flow equations always have smooth, globally defined solutions.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
