Target entity: Cartan matrix
Context triple: [semisimple Lie group, classifiedBy, Cartan matrix]

• A. Cartan decomposition
  Cartan decomposition is a fundamental structural result in Lie theory that expresses a Lie algebra or Lie group as a direct sum or product of subspaces or subgroups with specific symmetry properties, widely used in differential geometry and representation theory.
• B. Cartan–Killing form
  The Cartan–Killing form is a canonical symmetric bilinear form on a Lie algebra that plays a central role in classifying and studying the structure of Lie algebras and Lie groups.
• C. Coxeter–Dynkin diagrams chosen
  Coxeter–Dynkin diagrams are graphical representations that encode the structure of reflection groups and root systems, widely used in the classification of regular polytopes, Lie algebras, and symmetries.
• D. Cartan
  Cartan is a French surname most famously associated with mathematician Élie Cartan and his influential family of mathematicians.
• E. 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.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
