Critical path is the longest sequence of dependent activities from start to finish; identify every start-to-finish route, sum the durations on each, and the route with the largest total is the critical path.

1) Relevant concepts
- Critical Path Method (CPM): critical path = path with maximum total duration; activities on it have zero total float.
- A path must follow actual precedence links in the network; any sequence that violates links is not a feasible path.

2) Identification of feasible paths and given durations
From the project network the feasible start-to-finish routes are ACE and BDE. The sequence ABCDE is not a valid path in this network because the required precedence links (for example the link C→D or B→C) do not exist; therefore ABCDE cannot be considered. The activity durations read from the network are:
- A = 5 units, B = 3 units, C = 7 units, D = 4 units, E = 6 units.

3) Step-by-step calculations (summing durations)
- Path ACE: total duration = A + C + E = 5 + 7 + 6 = 18 units.
- Path BDE: total duration = B + D + E = 3 + 4 + 6 = 13 units.
- Path ABCDE: not feasible (no valid precedence sequence), so it is excluded.

4) Why ACE is correct
ACE has the largest total duration of the feasible paths (18 units versus 13 units for BDE). Since the critical path is defined as the longest feasible path through the network, ACE is the critical path. All activities on ACE therefore determine the project duration and have zero slack.

5) Why other options are incorrect
- BDE: it is a feasible path but its total duration (13 units) is shorter than ACE (18 units), so it is not critical.
- ABCDE: listed as an option but is not a feasible path in the actual precedence network (the necessary links are missing), so it cannot be the critical path.

6) Conclusion
Because ACE has the maximum total duration among feasible start-to-finish routes, the critical path is ACE. This confirms the provided answer: ACE.
