Triple

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 coordinates | Statement: [Eddington–Finkelstein coordinates, relatedTo, Schwarzschild coordinates]

Target entity: Schwarzschild coordinates
Context triple: [Eddington–Finkelstein coordinates, relatedTo, Schwarzschild coordinates]

• A. Schwarzschild coordinates chosen
  Schwarzschild coordinates are a spherical coordinate system used in general relativity to describe the spacetime geometry outside a spherically symmetric, non-rotating mass, such as a static black hole.
• B. 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.
• C. 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.
• D. 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.
• E. Kerr metric
  The Kerr metric is the exact general relativity solution describing the spacetime geometry around a rotating, uncharged black hole.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
