What is the output of the following code? #include int cnt =0; int my_function(int n, int sm) int i, tmp_sm; for(i=1;i<=n;i++) tmp_sm = recursive_sum_of_digits(i); if(tmp_sm == sm) cnt++; return cnt; int recursive_sum_of_digits(int n) if(n == 0) return 0; return n % 10 + recursive_sum_of_digits(n/10); int main() int n = 20, sum = 3; int ans = my_function(n,sum); printf("%d",ans); return 0;

Answer: Option C
