Phrase: Cartan’s method of equivalence | Statement: [Pfaffian form, studiedIn, Cartan’s method of equivalence]

Target entity: Cartan’s method of equivalence
Context triple: [Pfaffian form, studiedIn, Cartan’s method of equivalence]

• A. Vessiot theory of differential equations
  The Vessiot theory of differential equations is a geometric framework that studies differential equations via their symmetry and structure using concepts from Lie groups and differential geometry.
• B. Cartan connections
  Cartan connections are a geometric framework generalizing affine and Riemannian connections that model curved spaces on homogeneous spaces, developed by Élie Cartan.
• C. theory of G-structures chosen
  The theory of G-structures is a framework in differential geometry that studies geometric structures on manifolds defined by reductions of the frame bundle to a Lie group G, encompassing and unifying many classical geometries such as Riemannian, symplectic, and complex structures.
• D. Oka–Cartan theory
  Oka–Cartan theory is a foundational area of complex analysis that studies the structure and properties of holomorphic functions and coherent analytic sheaves on complex manifolds, particularly Stein spaces.
• E. Cartan theorems A and B
  Cartan theorems A and B are fundamental results in complex analytic geometry that characterize coherent analytic sheaves on Stein spaces by guaranteeing the existence of enough global sections and the vanishing of higher cohomology.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
