Overloading the operator as a global function would be required if the left operand is not a class object or a reference to a class object. In this case, since the left operand is an int, the operator needs to be overloaded as a global function. Choices A, B, and D all involve the left operand being a class object, so overloading the operator as a member function would be more appropriate in those situations.
