A
10 minutes
B
15 minutes
C
30 minutes
D
45 minutes
AI Explanation
The correct answer is C) 30 minutes. The minimum period of time that the air supply for a self-contained breathing apparatus (SCBA) is required to last is 30 minutes. This requirement is set by the U.S. Coast Guard regulations for SCBA equipment used on commercial vessels. The regulation ensures that the SCBA provides a sufficient air supply for crew members to safely evacuate in the event of an emergency. The other answer choices are incorrect because 10 minutes (A) and 15 minutes (B) are too short, and 45 minutes (D) exceeds the minimum requirement.
