Which two families of fire extinguishing systems are used in aircraft?

Explanation:
Fire extinguishing systems in aircraft are categorized by how quickly and forcefully they discharge their agent. The two families are conventional and high-rate discharge. Conventional systems release the agent at a moderate rate, supplying a steady flood to the protected area. High-rate discharge systems dump a large amount of agent very quickly to rapidly suppress a developing fire, which is crucial in high-risk spaces like engine nacelles and APU compartments. The other choices refer to the type of extinguishing agent or the actuation method, not the overall discharge strategy of the system.
