Which of the following refers to the wrapping of data and its functionality…

Step 1: Understand the question. The question asks about the concept that involves wrapping data and its associated functions into a single unit. Step 2: Analyze Option A – Modularity. Modularity refers to breaking down a system into smaller, manageable modules. It is about organization, not bundling data and functions together. Step 3: Analyze Option B – Abstraction. Abstraction involves hiding complex details and showing only essential features. It does not involve wrapping data and functions into a single unit. Step 4: Analyze Option C – Encapsulation. Encapsulation is the process of bundling data and the methods that operate on that data into a single unit, such as a class. This directly matches the definition in the question. Step 5: Analyze Option D – More than one of the above. This option is incorrect because only encapsulation correctly describes the concept of wrapping data and functions. Step 6: Analyze Option E – None of the above. This is incorrect because encapsulation is a valid concept that matches the question. Conclusion: The concept that refers to wrapping data and its functionality into a single entity is encapsulation.
