Features of the critical path method (CPM) include:

1. I and IV only

2. I, II and III only

3. III and IV only

4. IV only

The correct answer is: I, II and III only

The critical path method (CPM) is a project management technique used to determine the longest stretch of dependent activities and measure the time required to complete a project. The key features of CPM include: 1. **Identification of Critical Activities**: CPM helps in identifying the critical activities that are crucial for project completion. This means that any delay in these activities will cause a delay in the entire project. 2. **Determining Project Duration**: Since it highlights the longest path of tasks that must be completed on time for the whole project to be finished, it allows project managers to assess the total duration required to complete the project. 3. **Resource Allocation**: Understanding which tasks are critical helps in allocating resources effectively, ensuring that those critical tasks are prioritized. 4. **Visualization of Project Metrics**: CPM provides a clear visual representation of the project schedule, which helps in planning, monitoring, and controlling the project. Given these features, the correct answer indicates that options I, II, and III are relevant characteristics of the CPM, while option IV on its own is not a key feature, but can be considered incidental to understanding project structure and timing. The selection of option B acknowledges the full inclusion of significant characteristics related to the critical path method.
