Modular curves and the Eisenstein ideal

Target entity: Modular curves and the Eisenstein ideal
Context triple: [Barry Mazur, notableWork, Modular curves and the Eisenstein ideal]

• A. Eichler–Shimura theory
  Eichler–Shimura theory is a foundational framework in number theory and arithmetic geometry that connects modular forms with the cohomology of modular curves and the theory of elliptic curves.
• B. Shimura varieties
  Shimura varieties are higher-dimensional algebraic varieties that generalize modular curves and play a central role in the Langlands program by connecting number theory, automorphic forms, and arithmetic geometry.
• C. Serre’s conjecture on Galois representations
  Serre’s conjecture on Galois representations is a landmark statement in number theory that predicts which two-dimensional mod p Galois representations of the absolute Galois group of the rationals arise from modular forms.
• D. Abelian Varieties with Complex Multiplication and Modular Functions
  "Abelian Varieties with Complex Multiplication and Modular Functions" is a foundational monograph by Goro Shimura that develops the arithmetic theory of abelian varieties with complex multiplication and their deep connections to modular and automorphic functions.
• E. Shimura reciprocity law
  The Shimura reciprocity law is a fundamental result in number theory that generalizes classical reciprocity laws by describing how values of modular functions at complex multiplication (CM) points transform under the action of Galois groups.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity description: "Modular curves and the Eisenstein ideal" is a landmark 1977 paper by Barry Mazur that uses the arithmetic of modular curves and the structure of the Eisenstein ideal in Hecke algebras to prove deep results about rational torsion points on elliptic curves over the rational numbers.
