In Object Oriented Programming, which elements are stored together within a class?

• A. Data
• B. Data and methods
• C. Objects
• D. Classes

Answer: (B)

In object oriented programming, a class encapsulates both the data attributes (the state) and the methods (the behavior) that operate on that data. This means the class groups what describes an object (its data) together with the functions that act on that data, forming a single blueprint. This encapsulation lets each created object hold its own data values while using the class-defined methods to interact with and modify that data. For example, a Patient class might define data like patientID and name and methods like updateAddress() or getAge(), all bundled in one reusable structure. Objects are instances of the class, carrying actual values, but the class itself defines the data and the operations that work on that data. Data alone misses the behavior, and objects or the class itself don’t capture both aspects in one place, so data and methods together are the correct pairing.
