please explain why is that so?

What is the correct function call for row 11 - select A, B, C or D? 01:/* Sort two numbers */02: #include 03: void MinMax(int *Value1, int *Value2); 04: 05: int main(void) 06: {07: int a, b; 08: 09: printf("Enter two numbers and I will sort them for you:"); 10: scanf("%d%d", &a, &b); 11: 12: printf("%d, %d ", a, b); 13: 14: return 0; 15:} 16: 17: void MinMax(int *Value1, int *Value2) 18: {19: int tmp; 20: 21:/* If value 1 largest then swap values */22: if(*Value1>*Value2) 23: {24: tmp=*Value1; 25: *Value1=*Value2; 26: *Value2=tmp; 27:} 28:} MinMax(&a, &b); MinMax(*a, *b); MinMax(a, b); MinMax(a[], b[])
