Where are the AFFF MOVs located?

The answer is correct because AFFF (Aqueous Film Forming Foam) MOVs (Manual Operable Valves) are typically found in areas where there is a higher risk of fire, particularly in locations containing flammable materials or machinery that can catch fire. The generator areas and incinerator rooms are critical parts of a vessel where high heat and potential ignition sources are present. Therefore, having AFFF MOVs installed in these areas allows for immediate access to fire suppression capabilities in case of an emergency.

In contrast, other locations mentioned, such as the engine room, bridge, control room, and fantail, may not require the same level of fire suppression readiness as those associated with generating power or handling waste, making option B the most appropriate choice.
