Which tool is used to display the schedule in a visual format that shows task dependencies and critical path?

Correct answer: Network Diagram

Option C is correct because a Network Diagram (also known as a Project Network Diagram or Precedence Diagramming Method chart) visually maps all project activities as nodes and their logical dependencies as arrows, enabling the calculation of the critical path and float for each task. Option A, the Resource Histogram, displays resource utilization over time and is used for resource leveling, not for showing task dependencies or the critical path. Option B, a Status Report, is a narrative or tabular communication artifact summarizing progress, issues, and forecasts, with no built-in dependency or critical-path visualization. Option D, a Gantt Chart, shows tasks on a timeline and can show dependencies via link lines, but it does not explicitly expose the network logic and critical path calculations the way a Network Diagram does, making it secondary to the Network Diagram for this purpose.
