A Gantt chart illustrates the schedule for Project 'Phoenix', detailing tasks, dependencies, and durations. Task A (duration 5 days) must complete before Task B (duration 3 days) can start. Task C (duration 4 days) can run concurrently with Task B. The project finishes when both B and C are done. If Task A is delayed by 2 days, what is the minimum impact on the overall project completion time?

The correct answer to the question "A Gantt chart illustrates the schedule for Project 'Phoenix', detailing tasks, dependencies, and durations. Task A (duration 5 days) must complete before Task B (duration 3 days) can start. Task C (duration 4 days) can run concurrently with Task B. The project finishes when both B and C are done.
