B) Crashing a project often reduces the length of long-duration, but noncritical, activities.
C) Activities not on the critical path can never be on the critical path, even after crashing.

Question

Quizplus · Accepted Answer

Crashing involves adding resources to critical tasks in order to shorten the project duration. This means that tasks on the critical path are the only ones that can be crashed. Therefore, option A and C are incorrect. Crashing a project may also involve reducing the duration of noncritical tasks if they are the only tasks with available crashing options. Therefore, option B is incorrect.
