The critical path is the longest path through the network and encompasses all the activities that must be completed on time to ensure that the project is completed on schedule. In this case, the critical path is A-D-E, which has a duration of 19 days. Activities A, D, and E are all on the critical path because they have no slack time. Activity B has some slack time, so it is not on the critical path. Activity C can also be completed with some slack time, so it is not on the critical path either. Therefore, the correct answer is B) A-D-E;19.
