Answer:

The correct answer is letter "A": ​the use of different activity time estimates.

Explanation:

PERT (Project Evaluation Review Technique) and CPM (Corporate Performance Management) are both methods that allow managers to calculate the real-time it will take to finish a project. Though, PERT uses 3-time estimates for each activity while CPM requires only 1-time factors for each activity.
