Consider the following loop, which processes a list of employees: for employee in employees:
Print(employee)
Print(f'{employee.earnings():,.2f}
')
Which of the following statements a), b) or c) is false?
A) In Python, this loop works properly as long as employees contains only objects that can be displayed with print (that is, they have a string representation)
B) All classes inherit from object directly or indirectly, so they all inherit the default methods for obtaining string representations that print can display.
C) If a class has an earnings method that can be called with no arguments, we can include objects of that class in the list employees, even if the object's class does not have an "is a" relationship with class CommissionEmployee.
D) All of the above statements are true.

- Statement A is false because it overlooks the requirement that the objects in the `employees` list must not only have a string representation (which is indeed necessary for the `print(employee)` part to work) but also must have an `earnings` method that can be called with no arguments, as indicated by the `employee.earnings()` call. Simply having a string representation does not guarantee that the `earnings` method exists or can be called without arguments.
