Phrase: Stiefel–Whitney classes | Statement: [Characteristic Classes, hasSubject, Stiefel–Whitney classes]

Target entity: Stiefel–Whitney classes
Context triple: [Characteristic Classes, hasSubject, Stiefel–Whitney classes]

• A. Stiefel–Whitney classes chosen
  Stiefel–Whitney classes are characteristic classes in algebraic topology that assign cohomology invariants to real vector bundles, capturing their topological and orientability properties.
• B. Pontryagin classes
  Pontryagin classes are characteristic classes associated with real vector bundles that capture topological information about the bundle’s curvature and play a central role in differential topology and geometry.
• C. Chern classes
  Chern classes are fundamental topological invariants in differential and algebraic geometry that classify complex vector bundles and capture their curvature and twisting properties.
• D. Characteristic Classes
  Characteristic Classes is a foundational mathematical text in differential topology and geometry that systematically develops the theory of characteristic classes for vector bundles and fiber bundles.
• E. Hirzebruch signature theorem
  The Hirzebruch signature theorem is a fundamental result in differential topology that expresses the signature of a smooth, compact, oriented 4k-dimensional manifold as a polynomial in its Pontryagin classes.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
