Phrase: hard Lefschetz theorem | Statement: [Hodge–Riemann bilinear relations, implies, hard Lefschetz theorem]

Target entity: hard Lefschetz theorem
Context triple: [Hodge–Riemann bilinear relations, implies, hard Lefschetz theorem]

• A. Hard Lefschetz theorem chosen
  The Hard Lefschetz theorem is a fundamental result in algebraic geometry and Hodge theory that relates the cohomology groups of a compact Kähler manifold via repeated cup product with the Kähler class, yielding powerful symmetry and duality properties.
• B. Lefschetz hyperplane theorem
  The Lefschetz hyperplane theorem is a fundamental result in algebraic geometry and topology that relates the topology (especially homology and homotopy groups) of a smooth projective variety to that of its hyperplane sections.
• C. Grothendieck–Lefschetz theorem
  The Grothendieck–Lefschetz theorem is a fundamental result in algebraic geometry that extends Lefschetz-type hyperplane theorems to a broad scheme-theoretic and cohomological setting, relating the geometry and Picard groups of a variety to those of its hyperplane sections.
• D. Hodge–Riemann bilinear relations
  The Hodge–Riemann bilinear relations are fundamental positivity and orthogonality conditions on the intersection form in Hodge theory that underpin results such as the hard Lefschetz theorem and the Hodge index theorem.
• E. Lefschetz
  Lefschetz is a surname most notably associated with Solomon Lefschetz, a pioneering mathematician in algebraic topology and geometry.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
