public static int func1(int m, int n)
{
If (m == n || n == 1)
Return 1;
Else
Return func1(m - 1, n - 1) + n * func1(m - 1, n);
}Given the code in the accompanying figure, which of the following method calls would result in the value 1 being returned?
A) func1(1, 0)
B) func1(1, 1)
C) func1(1, 2)
D) func1(2, 0)

The only condition that returns 1 is if m is equal to n or if n is equal to 1. 
Only option B satisfies the condition where m is equal to n, as well as the condition where n is equal to 1. 
Option A has n equal to 0 which violates the condition specified in the code. 
Option C has m not equal to 1 which again violates the condition specified in the code. 
Option D has n equal to 0 which again violates the condition specified in the code.
