Answer:
option (b) 5 days
Step-by-step explanation:
Data provided in the question:
Scheduled start of the activity placement = day 10
Duration of the activity = 4 days
The actual start day of the activity = day 12
The original schedule had a calculated total float = 7 days
Now,
the delay in the start of activity placement = 12 - 10 = 2 days
Therefore,
The recalculated total float for the activity, when updated, would be
= original schedule had a calculated total float - delay in the start of activity
= 7 days - 2 days
= 5 days
Hence,
the correct answer is option (b) 5 days
