Question 20

Correct answer: A

class Person:
    def __init__(self, fname, lname):
        self.firstname = fname
        self.lastname = lname
 
 
class Student(Person):
    def __init__(self, fname, lname, year):
        super().__init__(fname, lname)
        self.graduationyear = year
 
 
x = Student('Paul', 'Wellert', 2021)

A. A subclass in object-oriented programming is typically more specialized than its superclass. This means that it inherits attributes and behaviors from its superclass but can also have additional features or functionalities that are specific to the subclass. This specialization allows for more specific and targeted implementations in the subclass.

B. A subclass is not more general than its superclass in object-oriented programming. The purpose of creating a subclass is to provide a more specialized version of the superclass with additional features or modifications. The subclass can inherit and extend the functionality of the superclass, making it more specific and tailored to certain requirements or use cases.

C. A subclass is not a twin of its superclass in object-oriented programming. While a subclass inherits properties and methods from its superclass, it can also have its own unique characteristics and behaviors. This differentiation between the superclass and subclass allows for customization and extension of functionality in the subclass without affecting the superclass.
