Target class: unitary matrix
Context triple: [Cabibbo–Kobayashi–Maskawa matrix, instanceOf, unitary matrix]

• A. even unimodular lattice
  An even unimodular lattice is a free abelian group of finite rank equipped with a positive-definite symmetric bilinear form whose Gram matrix has determinant 1 and for which the squared length of every lattice vector is an even integer.
• B. binary operation on matrices
  A binary operation on matrices is a rule that combines two matrices of compatible dimensions to produce a single matrix, such as matrix addition or multiplication.
• C. uniform system
  A uniform system is a conceptual model in which properties such as composition, structure, and behavior are assumed to be consistent and invariant throughout the entire system.
• D. scattering matrix chosen
  A scattering matrix is a mathematical construct that relates the amplitudes of incoming waves or particles to those of outgoing ones in a physical system, encapsulating how the system scatters or transforms incident signals.
• E. inner product space
  An inner product space is a vector space equipped with an inner product, a function that assigns a scalar to each pair of vectors in a way that generalizes the dot product and induces notions of length and angle.
• F. None of above.
