Which term describes a programming entity that groups data and methods together?

• A. Object
• B. Class
• C. Function
• D. Module

Answer: (A)

Grouping data with the operations that act on that data is the essence of an object. An object contains state (its data) and behavior (its methods) in one unit, so you interact with an instance that holds its own values and can perform actions. A class, by contrast, is the blueprint for objects—defining what data and methods exist but not actually holding the specific data yet. A function is just a block of code that performs a task and doesn’t inherently bundle related data with related behavior. A module is a collection of code gathered for reuse, not a single data-and-method bundle. So the best fit for a programming entity that groups data and methods together is the object.
