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

The reason compliance techniques represent a situational use of force option that relies on physical intervention lies in their nature and application during an encounter. Compliance techniques involve physical measures taken to gain control over a subject, ensuring that they comply with lawful orders. These techniques can include joint locks, holds, or other restraining methods that require physical interaction between the officer and the suspect.

Situational use of force options are tactical decisions made by law enforcement based on the context and dynamics of an interaction. Although verbal commands and officer presence can be effective in certain situations, they do not constitute physical intervention, as they rely primarily on communication and authority rather than direct physical engagement. K9 assistance can involve a dog in the apprehension process, but it does not focus on the officer's physical interaction with the individual in the same way compliance techniques do.

Thus, compliance techniques specifically highlight the physical aspect of intervention, fitting the criteria define a situational use of force that is reliant on physical actions to achieve control and ensure compliance from the subject.
