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: Standard Model of particle physics | Statement: [Kobayashi–Maskawa paper on CP violation (1973), theoreticalFramework, Standard Model of particle physics]

Target entity: Standard Model of particle physics
Context triple: [Kobayashi–Maskawa paper on CP violation (1973), theoreticalFramework, Standard Model of particle physics]

• A. Standard Model chosen
  The Standard Model is the fundamental theory in particle physics that describes the known elementary particles and their interactions (except gravity) through quantum field theories of electromagnetic, weak, and strong forces.
• B. Salam–Weinberg model
  The Salam–Weinberg model is the electroweak theory that unifies the electromagnetic and weak nuclear forces within the Standard Model of particle physics.
• C. Grand Unified Theories
  Grand Unified Theories are theoretical frameworks in particle physics that attempt to merge the electromagnetic, weak, and strong nuclear forces into a single, more fundamental interaction at high energies.
• D. 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).
• E. 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.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
