PERT analysis computes the variance of the total project completion time as A. the sum of the variances of all activities not on the critical path. B. the variance of the final activity of the project. C. the sum of the variances of all activities on the critical path. D. the sum of the variances of all activities in the project.

C. the sum of the variances of all activities on the critical path.
