The related options are:
(a) Activity B has a free float of 10 days
(b) Activity B has a total float of 10 days.
Total float : the maximum amount of time an activity can be delayed from its early start without delaying the entire project
Free Float : the maximum amount of time an activity can be delayed without delaying the early start of any of its succeeding activities.
I chose option (a) but correct answer is indicated as (b).
Can anyone explain this.

This is the Q # 18 of Oliver F Lehmann's Q-75 Mock Test.
The Options are:
A. Activity B has a free float of 10 d.
B. Activity B has a total float of 10 d
C. Activity A has a free float of 10 d
D. Activity A has a total float of 10 d
Option # C & D can be removed straight way.
Now , out of Option # A & B :
The Free Float for Activity B = ES of Activity D - EF of Activity B -1 = 31 -21 -1 = 9 days
The Total Float for Activity B = LS of Activity B - ES of Activity B = 26 - 16 = 10 days
You may please refer to Page # 177 , Figure 6-18 PMBOK Guide Fifth Edition for the necessary concept.
So , the correct answer Option is Option # B. Activity B has a total float of 10 d
Hope this should be helpful.
