To find the critical path, we need to calculate the earliest start time (EST) and latest finish time (LFT) for each activity.

Activity A EST = 0, LFT = 3
Activity B EST = 3, LFT = 9
Activity C EST = 3, LFT = 5
Activity D EST = 3, LFT = 8
Activity E EST = 5, LFT = 7
Activity F EST = 3, LFT = 10
Activity G EST = 9, LFT = 13

The critical path is the longest path of activities with no slack time. In this case, the critical path is A-D-G with an expected completion time of 12 days (EST of A + expected duration of D + expected duration of G). Therefore, the best choice is B.
