Pick up the correct statement from the following:
The float may be positive, zero or negative
If the float is positive and the activity is delayed by a period equal to its total float, the completion of project is not delayed
If the float of an activity is negative, delay in its performance is bound to delay the completion of project
All the above
Correct Answer :
D. All the above
