A
1 hour
B
2 hours
C

D

AI Explanation
The correct answer is B) 2 hours. According to the regulations for offshore drilling units, each storage battery for emergency lighting and power systems must be tested every six months under actual connected load for a period of at least 2 hours. This requirement ensures that the emergency power system can maintain the necessary power supply for a sufficient duration in the event of a primary power failure. The other options are incorrect because 1 hour may not be long enough to thoroughly test the system, while 3 or 4 hours are unnecessarily long durations for the required testing.
