Which statement correctly describes the critical path in a project network?

• A. It is the shortest sequence of activities that can be delayed without delaying the project.
• B. It is the longest sequence of activities in a network that establishes the minimum project duration.
• C. It is the path with the most slack time.
• D. It is the path with the most resource requirements.

Answer: (B)

The critical path is the sequence of activities that determines the project’s duration. It is the longest path through the activity network, measured by total duration, so it sets the minimum time required to complete the project. Any delay on this path delays the entire project because those activities have no flexibility to slip without affecting the finish date. Other paths have slack, meaning they can be delayed without extending the project deadline. The critical path typically has zero total slack, and it may be one or more paths if several routes share the same maximum duration.
