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: Cabibbo–Kobayashi–Maskawa matrix | Statement: [Nicola Cabibbo, notableFor, Cabibbo–Kobayashi–Maskawa matrix]

Target entity: Cabibbo–Kobayashi–Maskawa matrix
Context triple: [Nicola Cabibbo, notableFor, Cabibbo–Kobayashi–Maskawa matrix]

• A. Cabibbo–Kobayashi–Maskawa matrix chosen
  The Cabibbo–Kobayashi–Maskawa matrix is a fundamental component of the Standard Model of particle physics that describes how quarks change flavor via the weak interaction and accounts for CP violation in the quark sector.
• B. Kobayashi–Maskawa theory
  The Kobayashi–Maskawa theory is a fundamental framework in particle physics that explains CP violation in the Standard Model through a three-generation quark mixing matrix (the CKM matrix).
• C. Cabibbo theory
  Cabibbo theory is a framework in particle physics that describes the mixing of down and strange quarks in weak interactions through a single mixing angle, laying groundwork later generalized by the CKM matrix.
• D. PMNS matrix
  The PMNS matrix is a unitary matrix in particle physics that encodes the mixing between neutrino flavor and mass eigenstates, governing the phenomenon of neutrino oscillations.
• E. Gell-Mann–Nishijima formula
  The Gell-Mann–Nishijima formula is a key relation in particle physics that connects a particle’s electric charge to its isospin and hypercharge, helping classify hadrons within the quark model.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
