Explanation:
Zero total float in a project schedule means that the project is on a critical path, and any delay in the activities on the critical path will directly impact the project's completion date. In such cases, it is important to understand the concepts of free float and independent float.
Free Float:
Free float is the amount of time that an activity can be delayed without delaying the early start date of any successor activity. It is the total amount of time that an activity can be delayed without affecting the project's completion date.
Independent Float:
Independent float is the amount of time that an activity can be delayed without delaying the early start date of any other activity in the project. It is the total amount of time that an activity can be delayed without affecting the early start dates of any other activities.
Answer:
The correct answer is option 'C' - free float and independent float both must be zero when an activity has zero total float.
This is because when an activity has zero total float, it means that it is on the critical path and any delay in its completion will directly impact the project's completion date. In such cases, there is no room for any delay, and hence both free float and independent float must be zero.
If an activity had non-zero free float, it would mean that it could be delayed without affecting the project's completion date, which contradicts the fact that it is on the critical path. Similarly, if an activity had non-zero independent float, it would mean that it could be delayed without affecting the early start dates of other activities, which again contradicts the fact that it is on the critical path.
Therefore, when an activity has zero total float, both free float and independent float must be zero to ensure that the project stays on schedule and any delay in the critical activities is avoided.
