Which reaction among the three does NOT traditionally involve fighting?

The reaction that does not traditionally involve fighting is the freeze response. In the context of defensive tactics and psychological reactions to danger, the freeze reaction is characterized by a temporary paralysis or immobility in response to a threat. This is a natural instinct that allows individuals to evaluate their surroundings and decide on the next course of action without engaging in conflict.

When people experience intense fear, the body sometimes opts to "freeze," essentially becoming still to avoid detection or to gather information about the threat. This contrasts with the fight or flight responses, which entail either actively confronting the threat or escaping from it. While the freeze response may be a precursor to either fighting or fleeing once the individual has assessed the situation, it itself lacks any action that would be considered fighting.

The other options involve direct responses to a threat: fight entails actively engaging the danger, flight refers to escaping from it, and flee is similar to flight but often emphasizes a frantic or urgent escape. Thus, the freeze reaction distinctly stands apart as it does not involve any combative actions.
