Which chart visually presents task durations and interdependencies in a timeline?

• A. Network Diagram
• B. Critical Path Method
• C. Milestone Chart
• D. Gantt Chart

Answer: (D)

Gantt charts visually map how long each task will take and how tasks depend on one another along a timeline. Each task appears as a horizontal bar whose length shows its duration, with the time axis across the top or bottom indicating start and end dates. Dependencies are shown with connecting lines, making it easy to see which tasks can run in parallel and how delays in one task affect others. This timeline-focused view is exactly what you’s looking for when you want to see durations and interdependencies at a glance.

Other charts serve different purposes: a network diagram emphasizes the sequence of tasks with nodes and arrows rather than a time-based bar layout; the critical path method is a scheduling technique used to find the longest path and overall project duration, not primarily a timeline of durations; and a milestone chart highlights key events rather than full task durations.
