The critical path is A-D-F, which takes 3 + 6 + 2 = 11 weeks. However, since C (5 weeks) depends on both A and B, and E (4 weeks) depends on C, the longest path is A-B-C-E-F, which takes 3 + 4 + 5 + 4 + 2 = 18 weeks. Therefore, the earliest completion time is greater than 13 weeks but less than or equal to 16 weeks.
