False Statement:

E. The duration of the critical path is the same as project duration: The duration of critical path is not same as project duration. Critical path is the shortest time possible to complete the project. This shorter duration critical path is called a sub- critical path.

True Statement:

A. The longest of all paths through the network is the critical path: It is a fact that critical path is the longest path through the network. This means that in critical path the sequence of activities defines the starting and ending dates and have no slack time and float time.

B. All activities on the critical path does not have slack: Activities in critical path have zero slack time as all activities proceed as per planning and sometime the task is completed even before time.

C. There must be at least two activities on a critical path: In critical path there should be two or more number of activities to form a network. Having only one activity do not make a complete network, for network minimum two activities must be there.

D. On a specific project, there can be multiple critical paths, all with exactly the same duration: Multiple critical paths can result into multiple dependency between different tasks that run for the same time duration.
