How many total recursive calls (not counting the original call) to fib will be made from the original call of fib(6)

hello your question is incomplete below is the complete question

Consider the recursive version of the fib method from the textbook shown below:

public static long fib(int n)

{

if (n <= 2)

{

return 1;

}

else

{

return fib(n - 1) + fib(n - 2);

}

}

How many Total recursive calls( not counting the original call) to fib(2) will be made from the original call of fib(6)?

a. 3

b. 4

c. 5

d. 2

answer : 5 ( c )

Explanation:

The total recursive calls to fib(2) that will be made from the original call of fib ( 6 ) is  : 5 . considering the recursive version of the Fib method above
