Changing the expected time for activity B from 14 weeks to 18 weeks will cause a delay of 4 weeks in that activity. This will cause a delay of 1 week in activity D, since activity D is dependent on activity B. Therefore, the project completion time will increase by a total of 3 weeks (the 4-week delay in activity B plus the 1-week delay in activity D). So the correct answer is C) It will increase by three or four weeks.
