D.Indirect Recursion.
Explanation:
Indirect recursion is when a method calls other method which calls the original method again.
For example:-
public static int mthd1( int n)
{
if (n == 0)
return 0;
else
return (mthd2(n-1));
}
public static int mthd2(int n2)
{ return mthd1( n2-1); }
This is an example of indirect recursion.Where mthd1 calls mthd 2 and mthd 2 calls mthd 1 again.
