What is a class in object-oriented programming?

A class in object-oriented programming is correctly defined as a blueprint for creating objects that encompass both data and methods. This definition captures the essence of object-oriented programming, where classes serve as templates from which individual instances or objects are created. Each class can define attributes (data) that represent the state of the object, as well as methods (functions) that define behaviors or actions that the objects can perform.

When an object is instantiated from a class, it inherits the structure, behaviors, and the state defined by the class, allowing for organized code that promotes reusability and modular design. This encapsulation of data and behavior is a fundamental principle of object-oriented programming, making classes essential for building complex software systems.

While other choices mention aspects of programming, they do not encapsulate the concept of a class. Functions, memory management tools, and graphical representations pertain to other areas of software development but do not define what a class is or its purpose in an object-oriented programming context.
