Question 27 (1 point) A simple project network has three activities, A, B, and C. A is an immediate predecessor of B and of C. Neither B or C has a successor. The activity durations are A=8, B=9, C=5. Find the critical path and its length. The critical path is A-B-C; duration 13. The critical path is A-C; duration 13. The critical path is A-B; duration 17 The is no critical path in this network. The critical path is A-B-C; duration is 22
