Active protection devices vs passive protection devices are defined as

• A. Active devices require action by the occupant; Passive do not
• B. Passive devices require action by the occupant; Active do not
• C. Both require action by the occupant
• D. Neither protect occupants

Answer: (A)

Active protection devices are those that need someone to take action to make them work. For example, grabbing and using a fire extinguisher or pulling a manual fire alarm activates protection. Passive protection devices function automatically and do not require occupant action, such as automatic sprinklers or fire-resistive walls and doors that contain a fire without anyone’s intervention. So, stating that active devices require action by the occupant and passive devices do not fits how these protections are designed to operate. The other possibilities would imply action is always required by both or by neither, which isn’t how these protections are defined.
