Phrase: Borel subalgebras | Statement: [affine Lie algebras, hasStructure, Borel subalgebras]

Target entity: Borel subalgebras
Context triple: [affine Lie algebras, hasStructure, Borel subalgebras]

• A. Borel subalgebras chosen
  Borel subalgebras are maximal solvable subalgebras of a Lie algebra that play a central role in the classification and representation theory of Lie algebras and algebraic groups.
• B. Cartan subalgebras
  Cartan subalgebras are maximal abelian subalgebras of a Lie algebra consisting of semisimple elements, fundamental for classifying and understanding the structure of Lie algebras.
• C. Bruhat decomposition
  Bruhat decomposition is a fundamental result in algebraic group theory that expresses a group as a union of double cosets indexed by elements of its Weyl group, revealing a deep combinatorial structure.
• D. Bott–Samelson theorem
  The Bott–Samelson theorem is a fundamental result in algebraic topology and geometry that provides a resolution of singularities for Schubert varieties via Bott–Samelson varieties, illuminating the topology and cohomology of flag manifolds.
• E. Borel–Weil theorem
  The Borel–Weil theorem is a fundamental result in representation theory that realizes irreducible representations of compact Lie groups as spaces of holomorphic sections of line bundles over their flag manifolds.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
