The distinction between active and passive fire protection systems is fundamentally based on their functionality and operation. Active systems are designed to require some form of action or response to function effectively; they include components such as sprinklers, alarms, and fire extinguishers that actively work to detect or suppress fire once it occurs. For example, a sprinkler system relies on activation after a certain temperature is reached, which constitutes an active response to a fire.

On the other hand, passive fire protection systems are focused on containment and do not require any action to provide their protective characteristics. These systems include fire-resistant walls, doors, and floors that are built into a structure to resist fire spread and maintain structural integrity. Because passive systems are inherently part of the building's construction, they remain effective without any need for activation.

The other choices present misunderstandings or oversimplifications about the nature of these systems. The notion that active systems only use water fails to encompass the variety of active measures available, while the idea that active systems are exclusively installed outside misrepresents their application in building safety. Lastly, the claim that active systems are more effective than passive systems overlooks the need for both types in a comprehensive fire protection strategy, as they complement each other in mitigating fire risks.
