Target entity: Wythoff Nim
Context triple: [Sprague–Grundy theorem, relatedTo, Wythoff Nim]

• A. Sprague–Grundy theorem
  The Sprague–Grundy theorem is a fundamental result in combinatorial game theory that assigns each impartial game position a nonnegative integer (its Grundy value), allowing such games to be analyzed and combined via nim-like addition.
• B. Hackenbush
  Hackenbush is a combinatorial game played on colored line-graphs, famous in recreational mathematics for illustrating concepts in game theory and surreal numbers.
• C. Kayles
  Kayles is a classic impartial combinatorial game in which players alternately remove one or two adjacent pins from a row, with the goal of making the last move.
• D. Winning Ways for your Mathematical Plays
  Winning Ways for your Mathematical Plays is a multi-volume book on combinatorial game theory that popularizes and systematically explores mathematical games and their underlying structures.
• E. Conway’s soldiers
  Conway’s soldiers is a mathematical puzzle and thought experiment in combinatorial game theory that explores how far checkers-like pieces can advance on an infinite grid under specific movement rules.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
