I need help in this following mcq

If the function fTwo() is called as shown below:

int x = fTwo (5);

What is the highest value the variable nRet will obtain throughout the function’s execution until right before returning the function’s result?

1 int fTwo(int nNum)
2 {
3     int i = 0, nRet = -1;
4     for(i = 2; i < nNum - 1; i++)
5     {
6         if(nNum == i * i)
7             nRet = i;
8        else if( (i - 1)*(i - 1) < nNum && nNum < i * i )
9             nRet = i - 1;
10     }
11     return nRet;
12 }
