A gooseneck vents and flame screens
B power ventilation
C a vent header system
D at least two ducts extending to the weather deck
AI Explanation

The correct answer is B) power ventilation. According to the regulations in the Code of Federal Regulations (CFR) for tank vessels, pump rooms carrying grade C liquid cargo, with machinery spaces below the freeboard deck, are required to have power ventilation. This is specified in 46 CFR 32.55-10, which states that power ventilation must be provided for pump rooms on tank vessels. The other options, such as gooseneck vents, a vent header system, or dual ducts, are not the specific requirement for this type of pump room configuration.
