Triple

Target class: second-order tensor
Context triple: [Cauchy stress tensor, instanceOf, second-order tensor]

• A. rank-2 tensor chosen
  A rank-2 tensor is a mathematical object that can be represented as a matrix whose components transform with two indices under a change of basis, generalizing linear maps and bilinear forms in vector spaces.
• B. (0,2)-tensor
  A (0,2)-tensor is a bilinear map that takes two vectors as input and returns a scalar, often representing objects like metrics or covariant tensor fields on a vector space or manifold.
• C. symmetric tensor
  A symmetric tensor is a multilinear map or multidimensional array whose components remain unchanged under any permutation of its indices.
• D. tensor
  A tensor is a multidimensional array of numerical values that generalizes scalars, vectors, and matrices to represent data or linear relationships across multiple dimensions.
• E. tensor field
  A tensor field is a mathematical object that assigns a tensor (a multilinear map or multidimensional array following specific transformation rules) to every point in a space or manifold, varying smoothly from point to point.
• F. None of above.
