Question 403 Deck General

The correct answer is A) 1 fire pump is the minimum required on a cargo vessel of 900 GT. According to the regulations set by the US Coast Guard, cargo vessels under 1,000 GT are required to have at least one fire pump installed. This is specified in 46 CFR 34.10-10, which states that all cargo vessels must have a sufficient number of fire pumps, with a minimum of one pump. Since the vessel in the question is 900 GT, which is less than 1,000 GT, the minimum requirement is one fire pump. The other answer choices are incorrect because they do not align with the regulatory requirement for a 900 GT cargo vessel.
