Phrase: Cohen–Macaulay rings | Statement: [Introduction to Commutative Algebra, hasSubject, Cohen–Macaulay rings]

Target entity: Cohen–Macaulay rings
Context triple: [Introduction to Commutative Algebra, hasSubject, Cohen–Macaulay rings]

• A. Cohen–Macaulay ring chosen
  A Cohen–Macaulay ring is a commutative Noetherian ring whose depth equals its Krull dimension, giving it especially well-behaved homological and geometric properties.
• B. Eisenbud’s Commutative Algebra
  Eisenbud’s *Commutative Algebra* is a widely used graduate-level textbook that develops modern commutative algebra with strong connections to algebraic geometry, featuring topics such as free resolutions, syzygies, and Castelnuovo–Mumford regularity.
• C. Castelnuovo–Mumford regularity
  Castelnuovo–Mumford regularity is an invariant in commutative algebra and algebraic geometry that measures the complexity of the minimal graded free resolution of a module or sheaf, often used to control vanishing of cohomology and bounds on generators.
• D. Auslander–Buchsbaum formula
  The Auslander–Buchsbaum formula is a fundamental result in commutative algebra that relates the projective dimension of a finitely generated module over a Noetherian local ring to the depth of the module and the depth of the ring.
• E. Hilbert’s syzygy theorem
  Hilbert’s syzygy theorem is a fundamental result in commutative algebra that describes the finite length and structure of free resolutions of modules over polynomial rings.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
