What is the difference between an attribute and a method in a class?

The correct choice emphasizes the fundamental concepts of object-oriented programming. An attribute represents a characteristic or property of an object, essentially acting as a variable that holds data associated with that object. For example, in a class representing a 'Car,' attributes could include 'color,' 'make,' and 'model.' Each instance (object) of that class will have its own values for these attributes.

On the other hand, a method is akin to a function that is defined within a class and is intended to perform actions or operations related to that specific class. When you call a method on an object, it can manipulate the object's attributes or execute behavior pertinent to that object's role in the program. Thus, for the 'Car' class, a method could be 'start_engine' or 'stop_engine,' which defines what happens when the action is invoked.

This distinction is critical to understanding how data is encapsulated and how behaviors related to that data are implemented in object-oriented programming. Being clear about the roles of attributes and methods helps in organizing code in a logical and functionally cohesive manner.
