In analyzing a logical chain of activities in a critical path method (CPM) schedule, what...

 Impact of Calendars on Total Float:

Differing calendars (e.g., working days, holidays, or shifts) assigned to activities can result in varying total float values within a logical chain.

Total float measures the flexibility of an activity and is calculated based on its calendar and logical dependencies.

 PSP Study Guide References:

The guide covers how calendar assignments influence float calculations and their potential to create disparities in a critical path​.

 Conclusion: The correct answer is B, as differing total float values typically indicate the use of different calendars for activities in the chain.
