Target class: soft-theorem
Context triple: [Low’s soft-photon theorem, instanceOf, soft-theorem]

• A. singularity theorem
  A singularity theorem is a result in general relativity that shows, under certain physical and geometric conditions, spacetime must contain singularities where curvature becomes infinite and classical physics breaks down.
• B. approximation scheme in gravitational theory
  An approximation scheme in gravitational theory is a systematic method for simplifying and solving the equations of gravity—such as Einstein’s field equations—by expanding physical quantities in small parameters (e.g., weak fields, slow motion, or small perturbations) to obtain successively more accurate, yet tractable, descriptions of gravitational phenomena.
• C. theorem in relativistic cosmology
  A theorem in relativistic cosmology is a rigorously proven statement, derived from the Einstein field equations and related physical assumptions, that characterizes the large-scale structure, dynamics, or evolution of spacetime and matter in the universe.
• D. nonlocal theory
  A nonlocal theory is a conceptual framework in which interactions or correlations between entities are not confined to adjacent points in space-time, allowing influences to occur instantaneously or over finite distances without a mediating local process.
• E. Wilson line
  A Wilson line is a gauge-invariant observable defined as the path-ordered exponential of a gauge field integrated along a curve, representing the phase acquired by a charged particle moving through a gauge field.
• F. None of above. chosen
