What area lies within the reactionary gap?

• A. Danger zone
• B. Balance displacement
• C. Leverage
• D. Joint manipulation

Answer: (A)

The reactionary gap defines the distance you need to observe, decide, and respond before an attacker can contact you. The area inside that space—the part within immediate reach where an attacker could strike or grab you—is the danger zone. It’s labeled danger because a lapse in reaction within this zone can lead to harm, so maintaining space and having a timely response are essential for safety. The other terms describe methods used to control or manipulate an opponent rather than describe the spatial concept of distance: balance displacement refers to shifting an attacker’s balance, while leverage and joint manipulation are techniques applied when you’re in close contact.
