Quizplus · Accepted Answer

The critical path is the longest path in the network diagram that determines the shortest possible duration to complete the project. In this case, the critical path involves the following activities: 
- Activity 1 (A): 5 days
- Activity 3 (C): 3 days
- Activity 6 (F): 4 days
- Activity 8 (H): 2 days
- Activity 10 (J): 1 day
- Activity 12 (L): 2 days
- Activity 13 (M): 2 days
- Activity 14 (N): 1 day
Total duration = 5 + 3 + 4 + 2 + 1 + 2 + 2 + 1 = 20 days
Therefore, the correct answer is B) 15, which is the duration of the critical path minus the duration of the first activity (which can start as soon as the project is initiated).
