Phrase: Witt group | Statement: [Ernst Witt, knownFor, Witt group]

Target entity: Witt group
Context triple: [Ernst Witt, knownFor, Witt group]

• A. Witt group of quadratic forms chosen
  The Witt group of quadratic forms is an algebraic structure that classifies nondegenerate quadratic forms over a field up to stable equivalence, with addition given by orthogonal sum and inverses given by taking opposite forms.
• B. Weil group
  The Weil group is an extension of the absolute Galois group introduced by André Weil to refine class field theory and play a central role in the formulation of the local and global Langlands correspondences.
• C. Brauer group
  The Brauer group is an algebraic structure that classifies equivalence classes of central simple algebras over a field (or more general schemes), playing a key role in number theory, algebraic geometry, and cohomology.
• D. Grothendieck group
  The Grothendieck group is an algebraic construction that formally turns a commutative monoid (often arising from isomorphism classes of objects like vector bundles or modules) into an abelian group, playing a central role in K-theory and modern algebraic geometry.
• E. Milnor K-theory
  Milnor K-theory is an algebraic K-theory constructed from fields using tensor powers of their multiplicative groups modulo Steinberg relations, playing a central role in modern algebraic geometry and number theory.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
