The best choice for the function prototype to overload the assignment operator = for a class is D, const className& operator=(const className&). This is because the assignment operator should return a reference to the object being assigned to (which is className&) and it should take a const reference to the object being assigned (which is const className&). By making the argument a const reference, it ensures that the original object being assigned is not modified.
