B. def __init__(self, title, author):
C. def __init__():
D. __init__(self, title, author):

Answer 1

The correct way to define an initializer method is Option B. The 'self' parameter represents the instance of the class and allows the method to access and modify the instance variables.

Step-by-step explanation:

The correct way to define an initializer method is Option B: def __init__(self, title, author). An initializer method is also known as a constructor in object-oriented programming and is used to initialize the attributes or properties of an object when it is created. The 'self' parameter represents the instance of the class and allows the method to access and modify the instance variables.

The __init__ method is a special method known as a constructor, and it's called when an object is created from a class. The self parameter is a reference to the current instance of the class, and it is mandatory for all instance methods, including initializers. The parameters title and author after self are additional parameters that the method takes to initialize the object's attributes.
