Correct option is C
In PERT (Program Evaluation and Review Technique), the time estimates are represented by the Beta distribution. This distribution is used because it is flexible enough to model the range of possible outcomes (optimistic, most likely, and pessimistic time estimates) in project management, making it ideal for representing the uncertainty and variability in activity durations. The Beta distribution allows for different shapes of the distribution curve depending on the relative positions of these estimates.
