A. All activities on a critical path are critical activities. B. A project network may have none, one, or more critical paths. C. A delay in critical activity surely delays the completion of project. D. Each critical activity has identical earliest and the latest start times.
In project management, a project network is a graph depicting the sequence of tasks and work flow for a project and it must have at least one critical path. Critical path helps to plan all tasks that must be completed as part of a project. It calculates the shortest project duration possible by lining up the longest sequence of dependent tasks necessary to complete the project. A project network can have one or more critical path. Since option B mentioned that a project network may have “no” critical path, this makes it the wrong statement, as a project network must have a critical path.

The correct answer to this question is B. Project management is the discipline of helping a team initiate, plan, execute, control, and complete projects to achieve specific goals and success metrics. A project network is a visual depiction of project elements and how they are related, and it must have at least one critical path.
A critical path helps you model projects by inputting all necessary factors involved in the project and then by outputting the optimal timeline for completing the project. The answer B mentions "none," which is false. You can have more than one critical path, however.
