AI Explanation
The correct answer is B) two hours.
According to the regulations for mobile offshore drilling units, each emergency generator on the unit must be run under a full load for at least two hours when tested. This ensures that the emergency generator can provide reliable backup power for an extended period in the event of a main power failure.
