Quizplus · Accepted Answer

The optimal schedule can be found by following the critical path, which in this case is A-B-D-F. The duration of this path is 22 hours. However, the total available working hours for the day is only 18 hours. This means that there will be a delay of 4 hours, which is the idle time at the paint work center. Therefore, the best choice is C, which is 4 hours.
