Answer:

Option (5)

Explanation:

Since, it is returning a value which is stored in a variable result which is of int type, that is why, III is wrong as it cannot return a string. Moreover, A mutator method is one which changes the value of a private member of a class and they don't return anything of any type. But the statement is returning a value of int type so, it cannot be a mutator method. So, I and III are not true. Since, object of book class is able to access that method , it must be a public method otherwise error would have displayed as objects of class has no access to their private members and can invoke public member functions only. So, II is true.
