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: Hilbert spaces | Statement: [Functional Analysis: Introduction to Further Topics in Analysis, topic, Hilbert spaces]

Target entity: Hilbert spaces
Context triple: [Functional Analysis: Introduction to Further Topics in Analysis, topic, Hilbert spaces]

• A. Hilbert spaces chosen
  Hilbert spaces are complete inner product spaces that provide the fundamental framework for modern functional analysis and many areas of mathematical physics.
• B. Banach spaces
  Banach spaces are complete normed vector spaces that provide a fundamental framework for functional analysis and the study of infinite-dimensional linear phenomena.
• C. Hilbert–Schmidt operators
  Hilbert–Schmidt operators are a class of compact operators on Hilbert spaces characterized by having finite Hilbert–Schmidt norm, playing a central role in functional analysis and operator theory.
• D. Foundations of Functional Analysis
  Foundations of Functional Analysis is a seminal mathematical text that systematically develops the core concepts and theorems of functional analysis, particularly in the tradition of the Riesz school.
• E. Gelfand triples (rigged Hilbert spaces)
  Gelfand triples (rigged Hilbert spaces) are a mathematical framework that extends Hilbert spaces to rigorously handle generalized eigenvectors and distributions, particularly in quantum mechanics and functional analysis.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
