    It's c.

    Explanation:

    Program Evaluation and Review Technique (PERT) is a method used in program management. It analyzes the time required to complete each task in a project and so tries to determine the minimum time to complete a project. It was developed by the US Navy in 1957.

    In PERT analysis:

    there are 3 time estimates for every activity: optimistic, pessimistic, and most likely you have to find the Critical Path. The Critical Path is the longest path of scheduled activities that must be met in order to execute a project. It is important to know because any problems on the critical path can prevent a project from moving forward and be delayed. Therefore only critical activities can contribute to the project variance.
