In Python, classes are used to implement abstract data types (objects) with their own attributes and methods. Which of the following is a correct implementation of a class for cars which has the attributes "model" and "year"? O class Car(object) self.model model self.year-year O class Car(object) def_init_(self, model, year): self.model model self.year - year O class Car(object, model, year): def init(self) self.model model self.year - year def Car__(self, model, year) self.model model self.year-year
