Explanation

Inergen (A) and FM-200 (C) are the two correct answers - both are widely deployed clean agents in data center fixed fire suppression systems. Inergen is a blend of nitrogen, argon, and CO2 that lowers oxygen concentration enough to extinguish fire while remaining survivable for a brief evacuation window. FM-200 (HFC-227ea) is a chemical clean agent that interrupts the combustion chain reaction and is one of the most prevalent replacements for Halon in modern data centers.

Why the distractors are wrong:

• FE-130 (B) is a real clean agent (HFC-23), but it's engineered for very low-temperature environments like freezer warehouses - not a standard data center choice.
• Halon 1211 (D) is a portable extinguisher agent, not a fixed suppression system agent; more importantly, Halon production was banned under the Montreal Protocol due to ozone depletion, so it is no longer specified for new installations.

Memory tip: Think "I Feel More" - Inergen and FM-200 are the two you want. Halon is history (banned), and FE-130 belongs in the freezer, not the server room.
