Overloading as a non-member function would be necessary if the left operand is not a class object or a reference to a class object. Therefore, if the left operand is an int, the operator must be overloaded as a non-member function. A and D are not necessarily valid reasons for overloading the operator as a non-member function, and B is already met with a member function overload.
