Which term refers to the distance you must keep to react effectively against a sudden threat?

• A. Balance displacement
• B. Danger zone
• C. Reactionary distance
• D. Reactionary gap

Answer: (C)

Maintaining a reactionary distance is about the space you need to effectively respond to a sudden threat. This distance provides time to perceive what’s happening, decide on a course of action, and initiate movement or disengagement before the threat closes in. It factors in your human reaction time and how far the threat can travel during that moment, so you’re not left reacting at the last second.

Balance displacement focuses on stability and footwork, not the amount of space needed to react. The danger zone describes a risky area around a person or object, not the specific distance required to respond. Reactionary gap is a closely related idea, but the term used here matches the intended wording of the concept as the measured space you maintain to react.
