The direction asks for the option that is NOT a synonym. 'Quarry' has two meanings: (1) an open-pit mine (2) prey/target being hunted. Synonyms for the hunting sense: Prey, Victim, Target. 'Pit' only relates to the mining meaning, not the hunting sense. Since most other options relate to the hunting meaning, A (Pit) is correct as it's NOT a synonym in that context.
