Answer 1

Explanation:

Critical Path:

From the activity network representation, it can be analysed that the minimum time to complete the project is the maximum of all paths from start to finish.
So, the longest path will represent the critical path for the network, and it will represent the minimum possible duration required to complete the project.
The critical path will be the longest path in the network requiring the maximum amount of time, but it will represent the minimum duration that is required to complete all the activities i.e. completion of a project.
