If your vessel is to carry ten portable foam fire extinguishers, you must maintain a supply of at least _______________.

AI Explanation
The correct answer is C) five spare charges. According to the U.S. Coast Guard regulations, vessels that are required to carry ten portable foam fire extinguishers must maintain a supply of at least five spare charges for those extinguishers. This ensures that the required number of working extinguishers is always available in case any of the existing ones need to be recharged or replaced. The other options are incorrect because having only one spare extinguisher or charge is not sufficient, and carrying ten spare charges would be an unnecessary excess.
