AI Explanation
The correct answer is C) 90%. Carbon dioxide (CO2) cylinders must be recharged when the cylinder charge weight is less than 90% of the stamped full weight charge. This is a requirement specified in the regulations governing the maintenance and inspection of CO2 firefighting systems on commercial vessels, as per the U.S. Coast Guard regulations. The other options are incorrect because 80% (A) and 85% (B) are below the 90% threshold, while 95% (D) is above the required minimum charge weight.
