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: Schwarzschild radius is coordinate singularity | Statement: [Kretschmann scalar, helpsShow, Schwarzschild radius is coordinate singularity]

Target entity: Schwarzschild radius is coordinate singularity
Context triple: [Kretschmann scalar, helpsShow, Schwarzschild radius is coordinate singularity]

• A. Schwarzschild radius chosen
  The Schwarzschild radius is the critical distance from the center of a non-rotating, spherically symmetric mass at which its escape velocity equals the speed of light, defining the boundary of a black hole.
• B. Kruskal–Szekeres coordinates
  Kruskal–Szekeres coordinates are a maximal extension coordinate system used in general relativity to smoothly describe the entire spacetime of a Schwarzschild black hole, including regions across the event horizon.
• C. Schwarzschild black hole
  A Schwarzschild black hole is the simplest theoretical black hole solution in general relativity, describing a static, spherically symmetric, non-rotating, uncharged mass with an event horizon defined by the Schwarzschild radius.
• D. Eddington–Finkelstein coordinates
  Eddington–Finkelstein coordinates are a coordinate system in general relativity that smoothly covers a black hole’s event horizon, avoiding the coordinate singularity present in standard Schwarzschild coordinates.
• E. Schwarzschild Penrose diagram
  The Schwarzschild Penrose diagram is a conformal spacetime diagram that compactly represents the causal structure of a non-rotating, uncharged black hole, including its event horizon and singularity.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
