Which term is a blueprint for an object?

• A. Client-Side Programming
• B. Commit
• C. Concurrency
• D. Class

Answer: (D)

In object-oriented programming, a class serves as a blueprint for creating objects. It defines the structure and behavior that the objects created from it will have—the data they store (attributes) and the actions they can perform (methods). Think of a class as a template, and each object as an instance built from that template. For example, a class Car might specify properties like color, make, and model, and methods like drive or honk. When you create objects from this class, you get specific cars—say, a red Toyota Corolla and a blue Honda Civic—each with its own values but sharing the same design. This is why the term described fits best: it directly represents the pattern used to produce concrete objects. The other terms refer to different concepts altogether: where code runs (client-side programming), recording changes in version control (commit), or executing multiple tasks at once (concurrency).
