Explanation

Crashing is the addition of project resources to complete effort-driven activities in faster time. By adding more labor the activity can be completed faster. Crashing is a schedule compression technique to obtain the greatest amount of compression for the least incremental cost. Crashing works for activities where additional resources will shorten the duration. Approving overtime, bringing in additional resources, paying to expedite delivery to activities on the critical path are examples of crashing. Answer option A is incorrect. An activity of fixed duration, such as printing 100,000 brochures in a printing press, won't be completed faster by adding more effort. Answer option D is incorrect. Activities need not be risk-free to use project crashing. Answer option C is incorrect. All effort- driven activities are susceptible to the Law of Diminishing Returns. By adding more labor the value of the yield of the work decreases because of the cost of the labor added to the project
