In network analysis, the Critical Path of a project is defined as
- AThe path with the maximum number of activities.
- BThe shortest path through the network diagram.
- CThe longest continuous sequence of activities that determines the minimum project duration.Correct
- DThe path that contains activities with the highest total float.

N/A
Step-by-step solution
1. Review the definition of the Critical Path in project network analysis. 2. Identify that it represents the longest continuous sequence of activities determining the minimum project duration. 3. Select Option (c) as the correct answer.
Explanation
The critical path is the longest sequence of tasks in a project plan that must be completed on time for the overall project to finish by its deadline. Because it takes the most time to complete, this path determines the shortest possible total time needed to finish the entire project.
Shortcut
To remember the concept of the Critical Path in network analysis, use the key phrase "Longest Path, Minimum Duration": - Longest Path: It is the longest continuous sequence of dependent activities in the network diagram. - Minimum Duration: It determines the shortest (minimum) total time required to complete the overall project. - Zero Float: Activities on the critical path have zero float (no flexibility or delay permitted).
Common mistake
A common mistake is selecting option B by confusing the concept of "minimum project duration" with the "shortest path" through the network diagram, forgetting that the critical path is actually the longest sequence of dependent activities in terms of duration. Another frequent mistake is selecting option D by confusing float concepts, as activities on the critical path have zero float rather than the highest total float.
Correct answer: C) The longest continuous sequence of activities that determines the minimum project duration.
