Final answer:
Out of the given instructions, 'isinstance(ford_f150, Automobile)', 'isinstance(ford_f150, Truck)', 'isinstance(ford_f150, object)', and 'type(ford_f150) == Truck' (assuming no quotes around Truck) will return True.
Step-by-step explanation:
The question is about determining the validity of different Python statements that check the type of an instance ford_f150 that belongs to a class Truck that inherits from Automobile.
The statement isinstance(ford_f150, Automobile) will return True because Truck is a subclass of Automobile, so an instance of Truck is also an instance of Automobile.
The statement type(ford_f150) == 'Truck' is incorrect because type should be compared to the class Truck, not the string 'Truck'.
The statement isinstance(ford_f150, Truck) will return True since ford_f150 is an instance of the Truck class.
The statement type(ford_f150) == Truck is correct without quotes around Truck, so this will return True.
The statement isinstance(ford_f150, object) will also return True because in Python all classes are derived from the base class object.
The statement type(ford_f150) == Automobile is incorrect because type will return Truck, not Automobile.
