Risksarrow_forwardI also know answer is d, but please explain each and every option why other option are incorrect too. Which of the following statements regarding PERT analysis is true?  Each activity has two estimates of its duration. Project variance is the sum of all activity variances. Project standard deviation is the sum of all critical activity standard deviations. Only critical activities contribute to the project variance. none of these is true.arrow_forwardScope creep and feature creep are two unfavorable outcomes that may result from this. To make the distinction between the two ideas evident, explain them. What is the primary reason behind these two issues? What happens in this project's worst-case scenario if these two unfavorable circumstances arise?arrow_forward
