A critical path allows a business to sequence and schedule. It allows them to do tasks concurrently to reduce lead times. The answer is 17 as that is the shortest path in which each task can be completed. Its not A or B as the lower part takes 15 days in itself.No?
the whole point of the critical path is for you to use the shortest one, they all lead to the same end anyway. what's the point of having critical paths if you have to do all of it? it defeats the entire purpose
