What term describes the concrete objects created from a class, such as the wizard objects built from a wizard class?

• A. Instances
• B. Variables
• C. Functions
• D. Interfaces

Answer: (A)

In object-oriented design, a class is like a blueprint that defines what a wizard is and what it can do. A concrete object created from that blueprint is an instance. Each wizard object you create from the wizard class is an instance of that class, with its own specific state (like name, health, and spells). So the term for these concrete objects is instances.

Variables are storage for data, functions are blocks of code that perform actions, and interfaces describe a contract of methods without providing a concrete object. You can have many instances of the same class, each with its own values, built from the same blueprint.
