Phrase: Mazur's control theorem | Statement: [Barry Mazur, knownFor, Mazur's control theorem]

Target entity: Mazur's control theorem
Context triple: [Barry Mazur, knownFor, Mazur's control theorem]

• A. Mazur control theorem chosen
  The Mazur control theorem is a fundamental result in Iwasawa theory that relates Selmer groups over infinite p-adic extensions to those over finite layers, allowing arithmetic information to be “controlled” across the tower.
• B. Mazur’s theorem on convex sets
  Mazur’s theorem on convex sets is a fundamental result in functional analysis that characterizes the structure and approximation properties of convex sets in Banach spaces, particularly via convex combinations of sequences.
• C. Zariski’s Main Theorem
  Zariski’s Main Theorem is a fundamental result in algebraic geometry that characterizes finite-type morphisms between varieties by relating birationality, normality, and the structure of fibers.
• D. Scott–Mazur theorem
  The Scott–Mazur theorem is a result in functional analysis that characterizes when a Banach space is reflexive in terms of the weak compactness of its closed unit ball.
• E. Fontaine–Mazur conjecture
  The Fontaine–Mazur conjecture is a central open problem in number theory that predicts which p-adic Galois representations of number fields arise from geometry or from automorphic forms.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
