Answer:
The correct answer is letter "C": Finish-To-Finish (FF)
Step-by-step explanation:
The Precedence Diagramming Method (PDM) is useful for keeping an agenda of the necessary activities of a project. The PDM establishes there are four (4) types of relationships linking those activities: Finish-To-Start (FS), Start-To-Start (SS), Finish-To-Finish (FF), and Start-To-Finish (SF).
The Finish-To-Finish (FF) relationship describes how activities can start at different times, thus, they will last different times but are scheduled to finish together.
