The critical path is the longest path, which includes all activities that must be completed on time in order to finish the project on schedule. In this case, the longest path is A-B-D-E with a total time of 32 days. Therefore, the activities that make up the critical path are A, B, D, and E. Option A and C have activity C on their critical path, but C has a slack of 3 days, which means it can be delayed without affecting the project completion time. Option D only includes activities A, D, and E on the critical path, but activity B with a duration of 12 days is not included. Option E is incorrect as at least one answer choice is correct.
