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?
✓ Correct Answer: Option C
Task A is on the critical path, as it impacts Task B. A 2-day delay in Task A directly delays Task B's start by 2 days. Since Task B's path is 3 days, and Task C's is 4 days, the new critical path would be A + B, resulting in a 2-day overall project delay.
