Which of the following is a situational use of force option that relies on physical intervention?

The correct choice is compliance techniques, as these methods specifically involve physical intervention to gain control over a subject while minimizing the risk of injury to both the officer and the individual. Compliance techniques include tactics such as joint locks, pressure points, and other maneuvers that encourage compliance without the use of lethal force. They are designed to be used in situations where an officer needs to physically restrain an individual who is resisting or poses a threat.

Verbal commands mainly focus on oral communication to influence behavior, relying on the subject's willingness to comply verbally rather than through physical means. Officer presence relates to the mere presence of law enforcement, which can deter criminal behavior but does not involve any physical intervention. K9 assistance involves using trained police dogs to assist with various law enforcement tasks, but this does not constitute a direct physical intervention by the officer. Compliance techniques stand out as they are specifically designed to be utilized in active physical intervention scenarios.
