Implement the 'reverseit' function to allow the following code to work. Be sure to use pointer notation, not array notation:
cCopy code
char str[] = "Hello";
reverseit(str);
printf("%s", str);

A) void reverseit(char *str) { /* Code to reverse the string */ }
B) char* reverseit(char str[]) { /* Code to reverse the string */ }
C) char reverseit(char *str) { /* Code to reverse the string */ }
D) void *reverseit(char str) { /* Code to reverse the string */ }
