A 1 minute
B 2 minutes
C 3 minutes
D 5 minutes
AI Explanation

The correct answer is C) 3 minutes. According to the regulations, cargo pump rooms on tank vessels handling grades A, B, or C liquid cargo must be equipped with power ventilation of the exhaust type. The regulations specify that this ventilation system must be capable of completely changing the air in the cargo pump room within 3 minutes. The other answer choices are incorrect because 1 minute would not be sufficient to completely change the air in the cargo pump room, and 2 and 5 minutes do not match the regulatory requirement of 3 minutes.
