The correct answer is: D. Identify the activities which can be delayed without affecting the total float of either the preceding or succeeding activities
Free float is the amount of time an activity can be delayed without delaying the start of any succeeding activities. It is calculated as the difference between the late finish date of the activity and its early finish date.
Free float can be used to identify activities that have slack and can be delayed without impacting the project schedule. This information can be used to establish priorities for activities, as well as to identify activities that may be at risk of delaying the project.
A. Identify the activities which can be delayed without affecting the total float of preceding activity is incorrect. Free float is the amount of time an activity can be delayed without delaying the start of any succeeding activities, not the preceding activities.
B. Identify the activities, which can be delayed without affecting the total float of succeeding activity is incorrect. Free float is the amount of time an activity can be delayed without delaying the start of any succeeding activities, not the preceding activities.
C. Establish priorities is incorrect. Free float can be used to identify activities that have slack and can be delayed without impacting the project schedule, but it cannot be used to establish priorities for activities.
