Consider the following function: int fun(int x, double y) { return (x + y)/2; } Assume the following declaration and initialization statements: int n = 2, k; double m = 9.5; Which one of the following statements calls the above function correctly? Yantnz: o k = int fun(int m, int n); Oint fun(m, n); k = fun(int n, int m); o k = fun, m)
