Explanation

Option D (25) is correct because the critical path is the longest path through the network - it represents the minimum time to complete the project. By summing activity durations along every path from start to finish using Finish-to-Start (F-S) relationships in the AON diagram, the longest continuous sequence of activities totals 25 time units, which drives the project end date.

Options A (22), B (23), and C (24) are wrong because they represent shorter paths through the network - near-critical or non-critical paths that have float/slack. Choosing the shortest or middle path is a common trap; the critical path is never the fastest route, it's the longest.

Memory tip: Think of the critical path as the "bottleneck chain" - like the longest line at an amusement park. No matter how fast the other lines move, you can't leave until the longest line clears. CP = Longest Path = Project Duration.
