Two general areas in which an officer's use of force is justified are to apprehend a subject and to...

• A. defend self or others
• B. enforce traffic laws
• C. protect property
• D. maintain public order

Answer: (A)

The main concept is that officer use of force is justified in two broad contexts: to apprehend or control a subject, and to defend oneself or others from imminent harm. Defending self or others fits the second context exactly—when there’s an imminent threat, a reasonable use of force is allowed to prevent injury or death. The other options involve scenarios where force might be used, but they aren’t the standard justification categories for use of force: enforcing traffic laws, protecting property, or maintaining public order aren’t by themselves the general bases for justified force. Thus, defending self or others is the correct justification.
