Handcuff describes which of the following?

• A. A medical device for immobilization.
• B. A chemical agent used for restraint.
• C. A type of firearm accessory.
• D. Temporary restraining devices used frequently to control a subject.

Answer: (D)

Handcuffs describe temporary restraining devices used to control a subject. They’re mechanical restraints placed around the wrists to limit movement, allowing safety and control during detention or transport by officers or security personnel. They’re specifically for securing a person in a timely, reversible way, not for medical treatment, chemical restraint, or weapon-related gear. The other options don’t fit because handcuffs aren’t medical devices, chemical agents, or firearm accessories; they’re tools for physical control.
