### Project Activity Table and Precedence Diagram Explanation#### Activity TableThe following table outlines the activities involved in a project at Carl Betterton’s construction company. For each activity, the immediate predecessors and the expected time (in days) required to complete the activity are listed.| Activity | Immediate Predecessor(s) | Time (days) ||----------|--------------------------|-------------|| A | – | 3 || B | A | 4 || C | A | 6 || D | B | 6 || E | B | 4 || F | C | 4 || G | D | 6 || H | E, F | 8 |#### Precedence Diagram FiguresThree figures represent different precedence diagrams for the project. The task is to identify which diagram accurately depicts the precedence relationships outlined in the table.1. **Figure 1** - Activity A leads to activities B and C. - Activity B leads to activities D and E. - Activity D leads to activity G. - Activities E and F converge to lead to activity H. 2. **Figure 2** - Activity A leads to activities B and C. - Activity B leads to activities D and E. - Activity C leads to activity F. - Activity D leads to activity G. - Activities E and F converge to lead to activity H.3. **Figure 3** - Activity A leads to activities B and C. - Activity B leads to activities D and E. - Activity C leads to activity F. - Activity D leads to activity G. - Activities E and F converge to lead to activity H.To determine the correct precedence diagram, consider the immediate predecessors and tasks for each activity as detailed in the activity table. The solution involves matching these details with the diagram's structure.
