Suggested Answer: B 🗳️
Total float is the time you can delay an activity without delaying the project end date, whereas free float is on each activity and does not affect the early start date of successor activities. Float, also called slack, is the amount of time an activity can be delayed without affecting any subsequent activities. There are two types of floats available: Free Float: It is the amount of time a schedule activity can be delayed without delaying the early start date of any immediately following schedule activities. Total Float: It is the total amount of time that a schedule activity may be delayed from its early start date without delaying the project finish date, or violating schedule constraint. Float is calculated by using the critical path method technique.
Incorrect Answers:
A, C, D: These are not accurate definitions of free float and total float.
