From Table 7.2, activities A, G, and H are on the critical path and have an expected duration of 5, 6, and 4 weeks respectively. Increasing their durations by 2, 3, and 4 weeks leads to their new expected durations of 7, 9, and 8 weeks respectively. As a result, the project's new expected completion time would be 41 weeks (30+5+7+9) instead of 35 weeks. The increase in completion time is 6 weeks, which falls within option C, greater than 4 weeks but fewer than or equal to 6 weeks.
