Quizplus · Accepted Answer

When calculating fib(7), there will be a total of 19 recursive calls made (not counting the original call). 
When calculating fib(6), there will be a total of 9 recursive calls made (not counting the original call). 
So, the difference between the two is 10. Therefore, the answer is B.
