The chart shows that the critical path is 21 days. By adding extra resources, we can shorten the duration of activities on the critical path. The maximum duration reduction for each activity on the critical path is 3 days, except for activity E, which can be shortened by 2 days. Therefore, the maximum duration reduction is 3 + 3 + 3 + 2 = 11 days. However, the reduction is limited by the duration of non-critical activities that depend on critical activities. In this case, activity G has a duration of 3 days and depends on activity F, which is on the critical path. Therefore, the maximum duration reduction is 11 - 2 = 9 days. Thus, the best choice is B, which represents a reduction of 9 days.
